At least 30 people have been killed and 18 injured after Russian forces struck two passenger buses in Kramatorsk, eastern Ukraine, on Thursday morning, according to updated figures released by Ukrainian prosecutors. The attack comes amid continuing Russian strikes on Ukrainian cities.

Russian forces attacked Kramatorsk, in Ukraine’s Donetsk region, at approximately 10am local time on 8 October, hitting an area where two scheduled passenger buses were carrying civilians.

The Donetsk Regional Prosecutor’s Office initially reported 12 fatalities and 14 injuries. In a subsequent update, prosecutors raised the death toll to 30 and the number of injured to 18.

The attack was also confirmed by the Kramatorsk City Council and Vadym Filashkin, head of the Donetsk Regional Military Administration.

According to preliminary findings from Ukrainian investigators, Russian forces may have used a UMPB D-30SN guided aerial munition. The precise weapon and circumstances of the attack remain under investigation.

Passenger buses caught in Russian bombardment

The two buses were operating regular passenger services when the strike occurred. Ukrainian authorities said passengers were on board, although detailed information about the victims, including their ages and identities, has not yet been released.

Photographs published by the regional prosecutor’s office show the aftermath of the attack, including severely damaged passenger vehicles. Emergency personnel and law enforcement officers were dispatched to assist the wounded, recover victims and document evidence.

The strike raises questions about the selection of the target and precautions taken to protect civilians. Under international humanitarian law, civilian vehicles and their passengers are protected from deliberate attack unless a vehicle becomes a military objective under the applicable legal rules.

The circumstances of Thursday’s strike, including whether the buses were directly targeted or struck during an attack on another location, have not yet been independently established.

Kramatorsk under increasing pressure

Kramatorsk remains one of Ukraine’s principal administrative and logistical centres in the part of Donetsk region still controlled by Kyiv. The city has faced repeated Russian bombardments as Moscow continues its military campaign to capture the remaining Ukrainian-held territory in Donetsk.

Its transport infrastructure serves residents who have remained despite years of fighting, including those travelling between neighbouring communities and those attempting to leave the region.

Regional officials have repeatedly urged residents to evacuate to safer areas of Ukraine as Russian bombardments continue. However, civilians remain in Kramatorsk and surrounding settlements, where everyday services, including public transport, continue to operate despite the danger.

Guided bombs and civilian protection

Russian forces have used guided aerial bombs against Ukrainian-controlled settlements near the front line. Such weapons can be released from aircraft at distances that reduce Russian pilots’ exposure to Ukrainian air defences.

The UMPB D-30SN, provisionally identified in the Kramatorsk attack, is a guided munition designed to reach targets beyond the immediate position of the launching aircraft. Its suspected use against an area containing occupied passenger buses will form part of the investigation.

Investigators will need to establish the intended target, the weapon used and the information available to those who planned and carried out the strike. These findings are relevant to determining whether the attack violated the laws of war.

Investigators examine civilian deaths

The Donetsk Regional Prosecutor’s Office is collecting evidence concerning the bombardment, including the type of munition used and the circumstances in which the buses were struck.

Establishing whether the vehicles were deliberately targeted, or whether the attack resulted from an indiscriminate or disproportionate strike, will be central to any assessment under international humanitarian law.

The identities of the victims and the full extent of the damage have yet to be established publicly. As of the updated figures issued by Ukrainian prosecutors on 8 October, 30 people were reported killed and 18 injured.
