Two policemen and four lawyers were among those killed in the attack, according to DPO Mardan.
Provincial Information Minister Mushtaq Ghani told Geo News that the attacker first threw a hand grenade and then his suicide vest detonated at the entry gate of the district and sessions court.
According to DPO Mardan Faisal Shahzad, the attacker was wearing a suicide vest which had 6-8 kilograms of explosives. The DPO further said that the policeman who was martyred had opened fire on the suicide attacker resulting in the vest detonating.
The area has been cordoned off by security officials and an investigation is underway.
Those injured in the blasts have been shifted to a nearby hospital for treatment.
The incident occurred a few hours after an attack was foiled in Peshawar’s Christian Colony early Friday morning in which four terrorists were killed.
Four suicide bombers with arms and ammunition had entered Christian Colony Warsak after hitting a security guard at 5:50 AM today, ISPR said.
Security forces promptly responded and cordoned off the area. Seven people including two FC soldiers, a police constable, two civil guards, one Levies official and one civilian were injured in the attack. One civilian and levies official were martyred.
On Thursday the ISPR held a press briefing highlighting the success of the Operation Zarb-e-Azab.
On August 8, 72 people mostly lawyers were killed after a suicide bombing at Quetta’s Civil Hospital. The blast took place when Balochistan Bar Association President Bilal Kasi’s body was being brought to the emergency department. He was gunned down at Mano Jan Road earlier that day.
