Parents of students injured in gun-battles between militant madrassa students and security forces in Pakistan have accused the Lal Masjid administration of forcefully keeping their children inside the radical seminary.

Parents of Jamia Hafsa students injured at the Lal Masjid clashes said in Islamabad that they had wanted their daughters to return home, but the Masjid administration had not allowed the students to leave the madrassa, private channel Geo news reported.

The parents, who were upset over the situation and regretted the governments security operation, said they had repeatedly requested the Lal Masjid administration to send their daughters home but the madrassa had refused to grant leave to the girl students.

A social worker who met the injured students said the girls had wanted to leave for their homes but their teachers had ordered them to stay in the madrassa, the Daily Times reported.

The government has deployed the army and imposed curfew around the Lal Masjid where at least 21 people were killed in gun-battles between militant madrassa students and security forces.

At least 100 students of the radical mosque surrendered on Wednesday before a fresh deadline set by the Pakistani government ended even as the two hardline clerics along with several other students remained holed up inside the complex.
