Gunfire, blasts rock Indian air base; 2 militants at large

Attack continues into second day at installation located close to country's border with Pakistan

Gunfire and blasts were heard on Sunday at an Indian Air Force base attacked by militants a day earlier, as security forces hunted two gunmen still at large in the sprawling facility near the border with Pakistan.

A senior federal police official confirmed the gunmen were still holed up in Pathankot air base in Punjab state, a day after the pre-dawn raid in which four attackers and six military personnel were killed.
