SRINAGAR (Reuters) - Two people were killed and six wounded on Friday when freedom fighters threw grenades and opened fire at a police station in Kashmir, Indian police and witnesses claimed. No group has claimed responsibility for Fridays attack, which killed a policeman and a civilian and took place in the busy Sopore town north of Srinagar. They fired indiscriminately on police station before throwing a grenade, Mohammad Ashraf, a witness, told Reuters. I saw people were running for cover. On Thursday, two freedom fighters and two Indian soldiers were killed in a fierce gun battle in south of Kashmir, police said. Indian intelligence officials say violence may be on the rise in Kashmir because hundreds of Pakistan-based fighters could have sneaked into India during the past few months.
