SRINAGAR, India (Reuters) - A series of grenade explosions rocked India's restive Kashmir region on Wednesday, wounding at least 17 people including six paramilitary soldiers. Separatist guerrillas hurled a grenade at a paramilitary patrol in a crowded marketplace in Srinagar, the summer capital of Jammu and Kashmir. The attack on the marketplace wounded 10 people, police said. Earlier on Wednesday, militants threw a grenade at a security picket in the Karan Nagar area of Srinagar, seriously wounding two pedestrians, they added. Suspected separatist guerrillas also tossed a grenade at a girls' school in Pulwama which exploded on the premises and injured five people, including two teachers. Pulwama lies 31 km (19 miles) south of Srinagar. Militants also lobbed a grenade at a paramilitary patrol near Pakherpora, 28 km (18 miles) southwest of Srinagar, but nobody was injured. More than a dozen militant groups are fighting for Kashmir's independence or merger with neighbouring Pakistan. Predominantly Hindu India, which controls two-thirds of Kashmir, accuses Moslem Pakistan of arming and training Moslem separatists. Pakistan, which rules the remaining one third, says it only provides political and diplomatic support.
