Terrorists stormed Bacha Khan University in Charsadda in northwest Pakistan on Wednesday.
Media reported that three gunmen entered the Bacha Khan University in Charsadda, northwestern Khyber Pakhtunkhwa province, and opened fire on students and teachers in classrooms and hostels.
The Bacha Khan University in Charsadda is about 50 kilometres (30 miles) from the city of Peshawar.
Reports say that firing was still going on inside the campus where students, teachers and administration staff are present.
According to some reports two explosions were heard inside the university.
Geo TV reports that five injured have been taken out from the university.
It further said that over 3000 students were present inside the university when the attack happened.
Security officials have cordoned off the area and students are being evacuated from classes.
Peshawar was the location of Pakistan`s deadliest ever extremist attack, when Taliban gunmen stormed an army-run school in December last year and slaughtered more than 150 people, most of them children, in an hours-long siege.
