On March 2, gunmen opened fire at Bashir Khan, an Intelligence Bureau inspector who was on his way to work on his motorcycle. His 13-year-old son was injured in the ambush.

On Feb 24, three policemen were killed and six injured when three heavily armed suicide attackers went on a shooting spree and hurled grenades at a police station in Peshawar. Hours later, a suspected terrorist was injured while planting a bomb. The brazen attack was carried out a day after a deadly car bomb killed over a dozen people and injured more than 20 in the city.
