KYIV, June 01 (Agencies): A Russian missile strike on a Ukrainian army training area killed at least 12 soldiers on Sunday and wounded more than 60 others, the Ukrainian army said.
"Today, on June 1, the enemy launched a missile strike on the location of one of the training units of the Ukrainian army," it said in a statement.
"As of 12:50 pm (0950 GMT), 12 people are known to have been killed and more than 60 wounded."
Meanwhile, Ukraine launched a "large-scale" attack against Russian military aircraft on Sunday, hitting a base in eastern Siberia thousands of kilometres (miles) from its border, a source within the Ukrainian security services said.
"Ukrainian security services are carrying out a large-scale special operation aimed at destroying enemy bombers far from the front, in Russia," the source said, adding more than 40 aircraft had been hit and a fire broke out the targeted Belaya air base.
In video that he posted on Telegram, drones could be heard flying overhead and a giant plume of smoke rising into the sky.
He said, though, that it was the first such attack in that part of Siberia - and added that the number of drones in the attack was unclear. The drones, he said, had been launched from a truck.
The Belaya, or Sredny, airbase is located near the village of Sredny, and hosts Tupolev Tu-22M supersonic long-range strategic bomber, according to open source details about Russia's armed forces.
There was also a Ukrainian drone attack in the Murmansk region of northern Russia, according to local officials. The Olenya airbase, which also hosts strategic aviation, is located in the Murmansk region, according to open source data.
