Unidentified armed men Tuesday threw hand grenades at a girls college in northwest Pakistan, injuring 14 students, police said.
Police officer Jehanzeb Khan said that the incident took place on the outskirts of Mardan, a city some 200 kilometers northwest of capital Islamabad.
Khan said that unidentified men riding a motorbike threw two hand grenades inside the Girls Degree College and fled.
The injured girls were transferred to a hospital in the area. Doctors said the injured are in stable condition.
No group claimed responsibility for the attack.
Taliban militants have carried out attacks on schools, especially girls schools, in the tribal regions and northwest in their campaign against the government. They are against girl's education.
This is the first time that a girls college was attacked in day time when it was open. Taliban usually attack schools in the night time.
The school was closed after the attack and people in the area strongly condemned the incident.
Residents said they saw a large number of police arrived at the area and launched a search operation.
