Officials in India-controlled Kashmir say a grenade attack has wounded at least three soldiers, including one who is critically injured.

No one has claimed responsibility for the blast Sunday in Sopore.

Kashmir is claimed in full by both India and Pakistan. Since 1989, Muslim separatists have been fighting for Kashmir's independence from Hindu-majority India or for a merger with Muslim-majority Pakistan. At least 50,000 people have died in the violence.

The nuclear-armed neighbors have fought two wars over the Himalayan region since gaining independence from Britain in 1947.
