[originaltext] Four gunmen have been killed as the Indian military hindered

Four gunmen have been killed as the Indian military hindered a pre-dawn attack on an air force base near the border with Pakistan, officials say.
    Two soldiers at the Pathankot base were also killed in a gun battle lasting several hours. The base is on the main highway leading to Indian-administered Kashmir.
    The incident came days after the Indian and Pakistani leaders met in Lahore to launch a surprise peace initiative.
    The gunmen wore Indian military uniforms and drove a stolen car when they launched the attack at 3:30.
    They entered living quarters at the base, but were contained there and so were unable to cause any damage to military hardware, said air force spokeswoman Rochelle D’Silva.
    The BBC’s Sanjoy Majumder in Delhi says it is not yet clear who the attackers were but suspicion is already falling on Kashmiri militant groups based in Pakistan.
    India says the group is backed by Pakistan, but Islamabad denies this.
