4 crew dead in Russian military helicopter crash

The Russian Defense Ministry says one of its helicopters has crashed in northwestern Russia, killing its entire crew of four.

The ministry said the Mi-8 helicopter went down Monday during a training mission near Ostrov in the Pskov region, about 600 kilometers (about 370 miles) northwest of Moscow.

The reason for the crash wasn't immediately known. A team of military experts headed to the area to investigate the crash.

The Mi-8, designed in the 1960s, has been the workhorse for both Soviet and Russian aviation and widely exported around the world. Thousands have been built.
