Two Ukrainian generals were killed in a Russian high-precision strike on the Donbass city of Kramatorsk on Tuesday, the Defense Ministry in Moscow said on Thursday, citing "updated data."

The ministry had earlier claimed that the strike targeted the temporary base of the Ukrainian Armed Forces 56th Motorized Infantry Brigade. Since then, the ministry has added that the base was hosting a "staff meeting" involving dozens of Ukrainian officers and foreign advisers.

The attack resulted in the deaths of "two generals, up to 50 officers of the Ukrainian Armed Forces, as well as up to 20 foreign mercenaries and military advisers," according to the Russian Defense Ministry's daily briefing.

The news came as Russian forces continue to repel Ukrainian attacks on their defensive positions in Zaporozhye Region as well as in Donbass. Ukraine has lost almost 800 servicemen in attempted assaults on various fronts over the past 24 hours, the Russian ministry claimed. It added that Russian forces had destroyed dozens of pieces of Ukrainian heavy equipment, including howitzers, armored vehicles and a tank.

Earlier this week, Kiev accused Moscow of striking a restaurant full of civilians in Kramatorsk, killing 11 people, including at least two children and injuring more than 60 others.

Ukraine's security service, the SBU, said it had arrested a local resident suspected of leaking intelligence to Russia before the alleged strike. The agency also claimed that the goal of the strike had been to kill civilians.

Russia has denied the accusations, insisting that it only hits military targets.

The developments came as several Western media outlets reported that Ukraine has suffered heavy losses in its much-touted counteroffensive, which some allies are said to have assessed as unsuccessful thus far.

The Financial Times reported on the same day that Kiev's Western backers have warned that further funding and support will depend on the results of the ongoing offensive. General Christopher Cavoli, NATO's top commander in Europe, reportedly said last week that Russia was still enjoying "the advantage of mass."

Western media told us that the Russia missile strike on a hotel in Kramatorsk yesterday killed only civilians. This was directly refuted by a (likely) Western soldier/mercenary on the scene (possibly South African or British based on accent) who stated that there were "soldiers under the rubble all over".

In one of the videos of the aftermath, a tattoo of a wounded man is clearly visible, indicating that he belongs to the 3rd Battalion, 75th Ranger Regiment of the US Armed Forces. Either an instructor, or a mercenary. Another video shows a man in a uniform with the emblem of the 101st Airborne Division of the US Armed Forces.
