Pakistani authorities have stepped up security at military and other sensitive installations following the weekend attack by militants on an air base that damaged three grounded aircraft and destroyed a fuel tanker, security officials said Monday.
A recently formed group, Tehreek-e-Jihad Pakistan, has claimed responsibility for Saturday's attack in Mianwali, a city in eastern Punjab province, where police have repulsed multiple attacks by another group, the Pakistani Taliban, in recent months.
