SRINAGAR (AFP) - Three freedom fighters and a female bystander were killed on Monday during a fierce gunbattle with soldiers in Kashmir, police said. Fighting broke out near Tral town, about 40 kilometres south of Srinagar, when Indian troops raided a suspected freedom fighters hideout. A woman was killed in the crossfire, a police spokesman said, adding that three troopers were injured. Two of the dead fighters were Pakistani nationals, he claimed. Meanwhile, the bodies of two women raped and murdered in Occupied Kashmir were exhumed Monday in a fresh bid to determine who killed them, a police spokesman said. The double rape and murder in May fuelled discontent in the Muslim-majority region, where many residents have long campaigned against rule from the capital, New Delhi. The bodies were exhumed by a team of doctors in presence of family members, the spokesman said. Police and paramilitary forces were deployed in strength Monday to prevent protests at the site of the exhumation in the southern town of Shopian. The killing of the 17-year-old girl and her 22-year-old sister-in-law became the focus for large pro-independence rallies. The two bodies were recovered from a shallow stream and police initially said the women had drowned, but later acknowledged they had been raped and murdered. Four officers were arrested and granted bail for destroying evidence in the case, and the dead womens families have said the assailants were members of the security forces. Authorities this month handed over the case to Indias top investigative agency, the Central Bureau of Investigations (CBI), after state police failed to crack it.
