A top Islamist militant commander has based himself with 40 fighters inside the radical Lal Masjid where at least 21 people have been killed in gunbattles between madrassa students and Pakistani security forces.

The unnamed commander belonging to Mehsud tribe and having vast fighting experience in the restive Afghanistan has managed to enter Jamia Hafsa with a group of 40 fighters to support the students of Lal Masjid against the Pakistan government, a source privy to the Masjid said.

The jihadis who entered the Masjid are well-equipped and well trained for situations like this, the source was quoted as saying by The Post daily.

One of the brothers of a Member of National Assembly from Federally Administered Tribal Areas is also accompanying the commander to strengthen the hands of radical students.

The Lal Masjid administration would be in a better position to take on the security forces after putting the girl students holed up inside the Madrassa in safe locations, sources said.
