Grenade attack injures sixteen in Moscow

MOSCOW — A grenade attack has injured 16 people, most of them prostitutes, in Moscow.

Early Thursday morning, an unidentified man threw the grenade at a group of people standing on a central Moscow street.

He then fled in a car.

Police believe the attack might have been part of a clash between rival criminal gangs over control of prostitution.

But they haven't ruled out the possibility that it's connected to the war in Chechnya, where Russian forces are battling separatist rebels.
