Peshware, pakistan (BBN)-At least twenty people were feared killed and 50 others injured in an ongoing gun and bomb attack on a university in northwestern Pakistan, a Pak minister Mushtaq Ghani said on Wednesday.

“There are five dead bodies in front of me,” said emergency official Bilal Faizi, speaking from the Bacha Khan University in Charsadda, reports the Hindustan Times.

“All of them have bullet wounds.” He did not clarify if the dead included any of the gunmen.

A group of terrorists stormed a university in northwest Pakistan on Wednesday morning, killing at least one teacher and injuring several others, Pakistani media reports said.

Two of the gunmen have been killed, police said, but other attackers are believed to be on the second and third floors of campus buildings and firing is still going on.

Deputy Inspector General Saeed Wazir said police believed that most of the students had been rescued but several gunmen remained at large inside the university.

The terrorists entered the campus of Bacha Khan University in Charsadda district of Khyber-Pakhtunkhwa province. Pakistani media quoted witnesses as saying that they had heard intense firing and explosions within the campus.

Reports said the terrorists killed a lecturer and injured several others, including security personnel. The Geo News channel reported that two security guards were also killed though there was no official word on casualties.

TV news channels reported that army commandos had entered the campus to counter the terrorists. Following the attack, authorities evacuated other educational institutions in Charsadda.

“Police told me that firing is continuing on the campus,” said Fazal Raheem Marwat, vice chancellor at the Bacha Khan university in Charsadda, roughly 50 km from Peshawar. “At the moment I have no details about the casualties from the attack.”

The attack coincided with a poetry competition organised at the university to mark the death anniversary of Khan Abdul Gaffar Khan or the “Frontier Gandhi”, who is also known as Bacha Khan. Hundreds of people had been invited to the event.

In December 2014, Taliban fighters stormed an army public school in Peshawar and gunned down more than 130 people, a majority of them students.
