Ukrainian Prime Minister Serhii Koretskyi said Russia struck the operating room of the Strazheska Institute of the National Academy of Medical Sciences in Kyiv, injuring one patient.

Two 14-year-old boys were killed when an explosive device detonated in the evening in the Konotop district of Sumy Oblast, according to the statement by Oleh Hryhorov, head of the Sumy Regional Military Administration. The children encountered the dangerous device in a field, suffered severe injuries, and died at the scene, the statement said.

In 2022, Russian forces occupied parts of Sumy Oblast, but Ukraine liberated the region in April. Russia intensified its offensive again in 2025. Today, mines, unexploded ordnance and Russian drones shot down over the region pose a danger, as their warheads can detonate after falling. Overall, 146 children in Ukraine have suffered mine-related injuries, former Interior Minister Ihor Klymenko reported in April. For example, two months ago, an 11-year-old boy and a 15-year-old boy in Sumy Oblast were injured when an explosive device detonated.

Hryhorov expressed his condolences to the parents and relatives of the victims and urged people to remain cautious:

“Please be as careful as possible and remind children: do not approach unknown or suspicious objects, touch them, or try to move them. Take care of yourselves and your loved ones,” Hryhorov said.

Demining efforts continue in Sumy Oblast

On 24 February 2022, Russian forces entered the territory of Sumy Oblast. The first battles in the region took place that same day. In particular, Russian forces attempted to break through to Sumy, but Ukrainian troops repelled the offensive. On 11 April 2022, Ukraine restored control over the entire Sumy region.

As early as 7 June 2022, deminers were working in the Konotop, Sumy, and Okhtyrka districts, according to the Government Portal. That day, they surveyed areas and neutralized explosive devices.

The work of deminers remains deadly dangerous. In September 2024, two pyrotechnicians from Dnipropetrovsk Oblast were hit by a mine while demining Sumy Oblast: one died, while the other was hospitalized. In July 2025, deminer Oleh Petrenko was killed during humanitarian demining operations in Shostka District when a Russian FPV drone detonated, the State Emergency Service of Ukraine reported. Another pyrotechnician was injured, the statement said.

Nevertheless, the work continues despite the danger. In 2025, State Emergency Service deminers in the Sumy Oblast found and neutralized 5,283 explosive devices, the agency said in April. Sumy Oblast ranked sixth among all Ukrainian regions by this figure.

Twenty-two percent of Ukraine’s territory is potentially contaminated with explosive devices — more than 133,000 square kilometers, former Interior Minister Ihor Klymenko reported in April this year. Since the beginning of the full-scale invasion, State Emergency Service and National Police deminers have surveyed more than 248,000 hectares of territory and found more than 1 million 112 thousand explosive devices, the statement said.

Ukrainian rescuers are still pulling bodies from a collapsed apartment block in Pryluky. A Russian missile strike on the five-story residential building in the city of Chernihiv Oblast that borders both Russia and Belarus killed 19 people, including five children, and injured 55, Ukraine's State Emergency Service reported on 7 October.

Russia hit Kyiv and a dozen other regions overnight. Air defense downed five ballistic missiles, 39 cruise missiles, and 117 drones, while missiles and drones hit 18 locations, the Air Force said. The nationwide strike killed at least 24 people, including four children.

Among the dead in Pryluky were three one-year-old boys, Oleksandr, Kyrylo, and Serhii, and eight-year-old Maksym, President Volodymyr Zelenskyy says. Seven of the injured are children. Some residents are still unreachable, and all emergency services are working at the site. Russia keeps using missiles against Ukrainian cities and civilians by deliberate choice, he states.

"My condolences to all the families and loved ones," Zelenskyy says.

The strike comes on Putin's birthday

The attack came on Russian President Vladimir Putin's birthday on 7 October.

"Continuing to use missiles against Ukraine, against our people, our children, is an absolutely conscious choice of terror. This is what Moscow chooses despite all our efforts with partners to bring peace closer," Zelenskyy says.

He urges partners to increase pressure on Russia and bolster defense support for Ukraine, saying it is important that world leaders understand this and that the world not remain silent.

A pattern of strikes on Chernihiv Oblast

Pryluky, about 150 kilometers east of Kyiv, lies in a region Russia has hit repeatedly. The overnight barrage also damaged civilian and utility infrastructure across the Pryluky community, the city council said.

Ukraine had seen the attack. The day before, Zelenskyy warned that intelligence indicated a massive Russian strike was in preparation. Russia fired about 70 missiles overnight, killing two people each in the capital Kyiv and in the cities of Kremenchuk and Oleksandriia in addition to the Pryluky dead.
