At least five people have been killed after a group of gunmen attacked a university in the northwestern Pakistani province of Khyber Pakhtunkhwa, during which two explosions have been also heard.
"There are five dead bodies in front of me," said emergency official, Bilal Faizi, speaking from the Bacha Khan University in Charsadda on Wednesday, adding, "All of them have bullet wounds."
Military spokesman Major General Asim Bajwa said on Twitter that two attackers had been killed.
"Two more terrorists who were firing from inside the Block cordoned by Army troops, shot (and) killed. Op continues."
It was not immediately clear if the two were included in the toll of five given by emergency official Faizi.
"Police told me that firing is continuing on the campus," said Fazal Raheem Marwat, vice chancellor at the university in the district, which is located roughly 50 kilometers (30 miles) from the provincial capital of Peshawar.
"At the moment, I have no details about the casualties from the attack," he added.
Local police official, Amjad Khan, who was outside the university, said firing was still going on inside the campus.
According local TV channels, three gunmen entered the Bacha Khan University and opened fire on students and teachers in classrooms and hostels.
Shabir Khan, a lecturer at the university, said most of the students and staff were in the classes when the firing began.
"We launched an operation inside the university and are trying to rescue the students and staff of the institution," said Deputy Inspector General Saeed Wazir.
The incident takes place more than a year after pro-Taliban militants stormed an army-run school in Peshawar and killed about 150 people, including 134 students, in December 2014. The massacre shocked and outraged a country already scarred by nearly a decade of attacks.
