KRAMATORSK, Ukraine (AP) — Officials at a vocational school in an eastern Ukraine city dismissed claims by Russia that hundreds of Ukrainian troops were killed in a missile strike there, saying Monday that a rocket merely blew out windows and damaged classrooms.

Russia specifically named the vocational school in Kramatorsk as the target of an attack in the almost 11-month war. The Russian Defense Ministry said its missiles hit two temporary bases housing 1,300 Ukrainian troops in the city, killing 600 of them, late Saturday.

Associated Press reporters visiting the scene in sunny weather Monday saw a four-story concrete building with most of its windows blown out. Inside, locals were cleaning up debris, sweeping up broken glass and hurling broken furniture out into a missile crater below.

A separate, six-story school building was largely undamaged. There were neither signs of a Ukrainian military presence nor any casualties.
