The bodies of the four militants gunned down in an encounter with security forces during the terror attack on the country's strategic air base in Pathankot were sent for post mortem today, while combing operations to "sanitise' the entire air base was on its last leg.

In all, six militants were killed in the attack which started in the early hours of Saturday.

While the bodies of four were found to be intact, the remaining two were blown into pieces. The bodies of four terrorists were brought to the civil hospital for the post-mortem examination, officials said adding that a team of four doctors would conduct the medical examination on them.

Meanwhile, the mop up operation continued today to fully sanitise the air force base. "Our work is in progress in the entire area,' Pathankot Senior Superintendent of Police (SSP) R K Bakshi said. Security officials said that the combing operations will continue at the forward base where seven security personnel and six terrorists were killed.
