MARDAN: Chief of Army Staff General Raheel Sharif on Friday arrived at Mardan Medical Complex to inquire the health of those injured in the twin blasts at Mardan district courts on early Friday morning. At least 13 people were martyred while 60 others injured when two bomb blasts hit District Kacheri, according to rescue emergency officials. The first attack was a suicide attack near the Kacheri gate. The second took place shortly afterwards in which the attacker was stopped from entering the gate. The attacker lobbed a hand grenade before exploding himself at the main gate of Mardan district courts, DPO Mardan told. Following the blasts, security forces arrived at the spot and cordoned off the area. An investigation is underway while the injured are being shifted to local hospitals. The incident occurred a few hours after an attack was foiled in Peshawar’s Christian Colony early Friday morning.
