TOPSHOT-UKRAINE-RUSSIA-CRISIS-MILITARY-SLAVYANSK

TOPSHOT - Four pro-Russian militiamen lay on the ground with hands tied after being arrested on suspicion of the implementation of MANPADS (Man-portable air-defense systems ) shots to a helicopter of the Ukrainian forces on May, 2, 2014 at a checkpoint near Slavyansk . Ukraine's defence ministry on Thursday raised the toll during an assault on the rebel-held town of Slavyansk to two of its helicopters shot down and two servicemen killed. Authorities say the pro-Russian insurgents used shoulder-launched rockets to bring down the two Mi-24 helicopters. Earlier, the interior minister said one of those killed was a helicopter pilot.
