At least three Pakistani police security personnel were killed and 22 others, including civilians, were injured when a convoy of the army came under attack in the Mir Ali sub-division of the North Waziristan district, reported Dawn. The local officials in the region, on Saturday, said that the convoy of security forces and employees of the Marri Petroleum Company was on its way from North Waziristan to Bannu when a rickshaw struck the team. The outlawed Tehreek-i-Taliban Pakistan (TTP) has claimed responsibility for the attack.
