MOSCOW, May 8 (Xinhua) -- A Ukrainian drone strike on the administrative building of the Southern Russia Air Navigation branch disrupted operations at 13 airports across southern Russia, the Russian Ministry of Transport said Friday.

Operations at the regional air traffic control center in Rostov-on-Don, which manages air traffic across southern Russia, were temporarily adjusted after the strike, the ministry said in a statement.

All personnel at the facility are safe while specialists are assessing the equipment's operational status, the statement said.

The ministry and the Federal Air Transport Agency are coordinating with airlines and airports to revise flight schedules and modify air traffic management procedures in the region. ■
