The Islamic International University of Islamabad has reopend its doors after a twin suicide bomb attack killed seven students and staff and injured dozens last Tuesday.
The bombers targeted both the male and female campuses in a simultaneous strike.
The violence prompted the government to close down educational institutions across the country, which have also reported back after the weekend.
The explosions are part of a series of recent militant attacks, which have spread fear through the country’s cities.
Observers view the recent wave of suicide bombings as retaliation against the Pakistan military’s offensive in South Waziristan, the mountainous border region, long seen as a Taliban stronghold.
Earlier, Pakistan claimed it killed 19 suspected militants and lost six soldiers in fighting inside a Taliban stronghold close to the Afghan border.
