As violent riots grip France, British political leader Nigel Farage warned Americans against repeating what he described as Europe's mass immigration failures, arguing that years of unchecked migration have transformed European cities and fueled unrest that could eventually spread elsewhere.

"People like me who were warning about this years ago have sadly been proven right, but the problems are gonna be here for a very, very long time," Farage told Fox News Digital in an interview. "Please, please don't make the same level of mistakes that we have," he said in his message to Americans.

Violent riots have erupted across parts of Europe in recent weeks, particularly in France, with Farage pointing to years of mass migration and failed political leadership as key factors fueling the unrest. The Reform UK leader singled out Emmanuel Macron, arguing that the French president should have mobilized the military to confront the violence, after education protests spiraled into riots, destruction and theft.

MACRON JETS OUT OF RIOT-TORN FRANCE FOR GULF TRIP AS POLITICAL PRESSURE MOUNTS

"Macron was asleep at the wheel, and it isn't just that he was at a concert," Farage said. "And whilst the French do have effective police forces, the scale of the uprising, I mean the mass looting, the mass looting and violence that took place in Paris was genuinely horrendous."

"Meloni's reaction was swifter and a better sign of leadership," Farage said, referring to the Italian leader deploying 500 military troops to Milan in response to recent riots. "But the problem is, for people like Macron, who have always said, any criticism of immigration, whether legal or illegal, makes you racist, they psychologically find it hard to face up to their own failures of policy."

Farage warned that the unrest he described in France and elsewhere in Europe could eventually erupt in Britain, pointing to demonstrations in London and questioning whether British leaders would respond more forcefully than Macron.

"You know, my real worry is they can happen in this country too," Farage said. "We've got the same hard left here. We've the same hate mobs that march, chanting in the streets of London, from the river to the sea."

"I'm concerned that these things could happen here. And I wonder whether a British prime minister has got any more courage than President Macron in France," he added.

Farage contrasted Europe's failure to control its borders with President Donald Trump's immigration crackdown in the United States.

"Look, whatever you think of President Trump's current policies, one thing he has done, and he promised he'd do. He's closed the southern border," Farage said.

Trump vowed Tuesday to treat potential rioters in the U.S. "very rough," pointing to the unrest in France, he said at a rally in Greenville, North Carolina, before being interrupted by a protestor in the crowd.

"They're crazy, these people. Look at that guy. He's a nutjob," Trump said, in reference to the protester.

He warned that he would crack down on potential threats, saying he would not allow similar unrest to take hold in the U.S.

"That's what you witness over the last three or four days. You watch nutjobs like him in France ruining their country," Trump said. "We're not going to put up with it by the way."

"If a possible threat, which could happen, I hope you won't get angry if I treat them very, very rough, because that's what's going to happen. They're not going to destroy our country," he said.

On Tuesday, British counterterrorism police rearrested two men suspected of assisting Iranian intelligence in an alleged plot targeting RAF Fairford, a U.K. base used by U.S. bombers.

Authorities say Iranian state involvement is "highly likely," though no charges have been filed.

Farage said he has foreshadowed such criminal acts, alleging that Iran has exploited illegal crossings of the English Channel to move operatives into Britain.

"I've called again and again for this to be declared a national security emergency. I have been ignored. If the Americans removing their bombers from RAF Fairford isn't enough warning. I don't know what is," he said.

"We've just become so caught up over here in Europe and Britain with this human rights culture, which puts the interests, frankly, of the bad guys above the interests of the majority."

Sea mines have resurfaced as a threat in the Strait of Hormuz, where Iran claimed Oct.17 that two oil tankers caught fire after striking the explosives, raising fresh alarms over the safety of one of the world's most critical shipping lanes.

This came as the International Maritime Organization (IMO) warned that sea mines pose a serious threat to vessels navigating the strategic waterway and while Tehran continues to maintain its own unauthorized shipping corridor inside its territorial waters.

"The traffic separation scheme, the information that we have is that they still have mines. And of course, whilst the conflict is ongoing, it's very difficult for us to use third parties to verify that it is clear of these hazards," IMO Secretary-General Arsenio Dominguez told Fox News Digital.

INSIDE THE DANGEROUS US MISSION THAT CLEARED IRAN’S MINES FROM HORMUZ SHIPPING LANES

"So in the meantime, we cannot guarantee that a vessel that intends to transit that route will not be hit by a mine."

Iran's Islamic Revolutionary Guard Corps (IRGC) navy said Saturday that two oil tankers caught fire after striking naval mines while crossing the Strait of Hormuz, Reuters reported, citing Iran's official Islamic Republic News Agency (IRNA).

State media also said both tankers were carrying about 2 million barrels of crude oil, according to Reuters.

IRNA also reported that the vessels had switched off their positioning and radar systems and attempted to use a route through the strategic waterway that Iran had not authorized.

The second tanker was left immobilized after striking a mine, according to the Reuters report.

The alleged strikes came as Tehran continued to maintain its transit passageway inside Iranian territorial waters, imposing tolls and safety fees administered by the IRGC — a framework rejected by Washington and the IMO as inconsistent with international maritime law.

International shipping through the narrow chokepoint has historically relied on an IMO-approved traffic separation scheme adopted in 1968.

"Right now there's only one route that was adopted back in 1968 that is approved and recognized for IMO and that appears in all the charts for the vessels to operate," Dominguez explained.

"There's only one route that should be used for transit, but it's not clear of mines right now, so it's not safe."

"We have received confirmation from Iran about the establishment of its temporary route in the waters," he added before stating that the route was not provided with "an official confirmation or a decision of the organization."

"Any other route needs to actually be sent to the organization to go through the processes, and we have not received that."

"We have received communication from Iran to use that route because of the conflict," Dominguez clarified.

"That's the way that it's been presented. But anything for us to approve needs to go through the mechanisms at the international maritime organizations and the member states need to review it."

The developments also came amid stalled negotiations between Washington and Tehran over ending the conflict and restoring maritime traffic.

Mohsen Rezaei, secretary of Iran's Supreme National Security Council and a former Revolutionary Guard commander, said Tehran considered Washington's latest response to negotiations "insufficient," Reuters reported, according to IRNA.

Rezaei said the U.S. had accepted some of Iran's seven conditions but that other issues remained unresolved, adding that Tehran was no longer responding to Washington and that the U.S. needed to clarify the outstanding matters.

Iranian Foreign Minister Abbas Araghchi said that Tehran had submitted a proposal to Washington through Qatar, which is mediating the negotiations, outlining conditions under which the Strait of Hormuz could reopen and normal maritime traffic resume within seven days.

"Our situation is clear and based on ⁠the seven-day proposal presented to the US. They shared comments which ​we are reviewing, but our proposal is still on the table ​and if there is any honesty on the US part, which there isn't, the way to reopening the Strait of Hormuz is obvious," Araqchi said in ​Baghdad, Reuters reported

Meanwhile, attacks on commercial vessels around the Strait of Hormuz have surged over the past two weeks.

Senior Iranian officials also told Reuters that Tehran has shifted its strategy for attacking commercial vessels during that period.

For commercial shipping operators, Dominguez warned that the continued threat of mines and attacks means the waterway has yet to return to normal operations.

The Strait of Hormuz is "not open for business in the way that it was before the conflict started," he said.

"Our role right now is to prepare for when we have the opportunity to go back, resume the operations, follow all the procedures at IMO, but not until the root causes are addressed and those are beyond IMO."

Fox News Digital reached out to U.S. Central Command (CENTCOM) for comment.

One of Saudi Arabia’s most iconic skyscrapers ordered office workers to stay home Sunday as escalating attacks by Iran-backed Houthi rebels rattled the capital of Riyadh amid fears of a widening Middle East conflict.

The move came after the Saudi-led coalition said it intercepted two drones in the Riyadh area, a third over the Eastern Province and two ballistic missiles in southern Saudi Arabia overnight, after authorities had earlier issued a threat alert in the capital, also shared on X.

Management at the 99-story Kingdom Centre, a landmark on Riyadh's skyline, ordered office employees to work remotely until further notice, according to reporting by Agence France-Presse (AFP).

The directive affects a building whose tenants include major international financial institutions such as Merrill Lynch, consulting giant McKinsey & Company and the International Monetary Fund.

THE HOUTHIS AREN'T SOMEBODY ELSE'S PROBLEM. AMERICA CAN'T AFFORD TO LOOK AWAY

"Please be advised that remote working arrangements are mandatory for all office employees at Kingdom Centre, effective immediately and until further notice," building management said in an email obtained by AFP.

Employees were instructed not to report back to their offices. The shopping mall at the base of the tower, however, remained open to the public.

Management did not specify a reason for the directive, but it came as repeated missile and drone attacks by Yemen's Houthis disrupted the Saudi capital.

The security concerns also follow a deadly Oct. 10 attack on King Khalid International Airport that killed 13 people and wounded more than 300 others.

As previously reported by Fox News Digital, another strike the following day killed one person and injured 11.

Airport operations have been severely disrupted, while schools in Riyadh have extended remote learning measures amid continued security threats.

SAUDI ARABIA FACING 'BIGGEST THREAT' EVER TO OIL PRODUCTION AS IRAN-PROXY HOUTHIS LAUNCH ATTACKS, EXPERT SAYS

The mounting crisis comes as Saudi Arabia's military reported two deaths in a helicopter crash near its southern border with Yemen.

Maj. Gen. Turki al-Maliki, spokesperson for the Saudi-led coalition, said Sunday that an AH-6i reconnaissance helicopter crashed in the Najran region because of a technical malfunction, killing both crew members.

Saudi civil defense authorities also reported Sunday that six people were injured when a hostile projectile struck a residential neighborhood in Najran, damaging three homes and three vehicles.

Meanwhile, Egypt moved toward potentially providing military assistance to Saudi Arabia as the kingdom confronts the growing Houthi threat.

Egyptian President Abdel Fattah el-Sissi requested an emergency parliamentary session to authorize defensive military support for Saudi Arabia if requested by Riyadh, Reuters reported.

Lawmakers were expected to continue discussions Monday.

The Egyptian presidency said Cairo was prepared to provide Saudi Arabia with necessary support to defend its security, stability, territorial integrity and Islamic holy sites.

The statement followed a meeting of Egypt's National Defense Council chaired by el-Sissi and attended by senior government and military officials.

Egyptian Foreign Minister Badr Abdelatty also spoke with Saudi Foreign Minister Prince Faisal bin Farhan about regional developments and the importance of de-escalation, according to a post on X.

The potential involvement of Egypt, which has one of the Arab world's largest militaries, could significantly expand the regional response to the Houthis.

The Iran-backed group now controls Yemen's capital, Sanaa, and much of the country's north.
