A fresh wave of terror gripped Pakistan today when suspected Taliban bombers struck a key air force base and an upmarket restaurant and blew up a bus ferrying a marriage party, killing at least 26 people. As clashes intensified in lawless tribal belt of South Waziristan, militants brought the fight to military's front door again when a cycle-borne suicide bomber blew himself up at a security check point of Pakistan Aeronautical Complex at Kamra in Punjab province, killing eight people, including two air force guards, and injuring 15 others in an early morning raid. Kamra is Pakistan Air Force's largest maintenance and research base and this was the second assault on the facility reportedly linked to the country's nuclear weapons programme. The first attack had occurred in December 2007. Reports say , the base also houses combat jets equipped to carry nuclear warheads.According to US intelligence think-tank Stratfor, the strike against the Kamra complex is likely to raise renewed concerns about the safety of Pakistan's nuclear weapons. Hours after the Kamra attack, militants exploded a landmine under a bus ferrying a marriage party killing at least 18 people, including women and children, and injuring six others in Pakistan's restive Mohmand tribal region.The incident occurred in Lakaro sub-division, a remote region of Mohmand Agency where security forces are conducting operations against militants. Another suspected Taliban militant detonated a car bomb outside a restaurant in the northwestern Pakistani city of Peshawar, injuring at least 15 people. Reports said the restaurant targeted in the attack belonged to the son of a senior leader of the Awami National Party, which is in power in North West Frontier Province and is part of the ruling coalition at the centre.
