At least 15 people had been killed and dozens wounded, when a bomb  ripped through a government bus in Peshawar.

Police stated that the explosives were hidden inside a toolbox and had been detonated remotely. The improvised explosive device was planted under a seat in the bus. The bus was privately hired and used to bring government employees from Mardan to Peshawar. It was supposed to take some government employees to the Provincial Secretariat in Peshawar.

SP Cantonment Kashif Zulfiqar, said, “The blast was caused by a timed-improvised explosive device (IED) planted in a tool box inside the bus.”

Police official Abbas Majeed Marwa said that the bombing took place in an area surrounded by military institutions and residences.

According to Independent, around 40 people were wounded in the blast. 8 people were in critical condition.

No one immediately claimed responsibility but the authorities are suspecting Pakistani Taliban and other allied groups behind the criminal act.  These militant groups are fighting more than a decade to overthrow the government and establish their own ruthless brand of Islam. Peshawar and surrounding tribal areas in the Pakistan-Afghanistan border have several Islamic militant groups.

Local TV showed the badly garbled bus, as police official and rescue team rushed the wounded to hospital. It was reported that some windows of nearby buildings were also smashed and damaged but no bystanders were hurt.

Police Superintendent Kashif Zulfiqar said, “About 50 government employees were present inside the bus that was hired to pick them up and carry them to their office in Peshawar.”

The Prime Minister Nawaz Sharif strongly condemned the attack. He stated, “these cowardly attacks cannot shatter our unflinching resolve against terrorism.”

It was the third such attack, reported The Guardian. In 2013, 19 people were killed and 42 injured when a suicide bomber boarded a bus carrying government employees.

In January, some militants entered the Bacha Khan University in Charsadda, northwestern Khyber Pakhtunkhwa province, and shot students and teachers in classrooms and hostels.
