Four gunmen have been killed as the Indian military thwarted 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 Narendra Modi and Nawaz Sharif met in Lahore to launch a surprise peace initiative.
The whole of India's Punjab state has been placed on alert.
