Kashmir grenade attacks injure 52

Violence has increased in Kashmir recently

SRINIGAR, India (CNN) -- At least 52 people were wounded on Friday in grenade attacks in two Indian-administered Kashmir towns, police say.

A grenade was tossed into a market in Shopian, wounding 35 people, while a second grenade was thrown at a bus shelter in Anantnag, injuring 17 people, including two security people.

Separatist violence has surged in recent weeks across the Himalayan state of Jammu and Kashmir, a contested area between India and Pakistan.

Shopian is 50 km (30 miles) south of Srinagar, the summer capital of the Himalayan state.

None of the handful of rebel groups fighting Indian rule in the Muslim-majority state have claimed responsibility for the attacks.

On Thursday, 14 people were injured when militants hurled a grenade at a bus station in south Kashmir.

More than 33,000 people have died since Islamic rebels seeking either independence or union with Pakistan launched the revolt in late 1989.
