A helicopter belonging to Ukraine's state gas company crashed as it tried to land on a Black Sea drilling platform, killing all 20 people aboard, officials said.
The Mi-8 helicopter went down about 40 miles offshore, said Valentyn Zemlyansky, a spokesman for the company, Naftogaz. The craft's tail hit a support pole on the rig, and then the copter fell onto the rig and caught fire, the Emergency Situations Ministry said.
