ISLAMABAD, Pakistan (AP) - A suicide bomber attacked a military checkpoint in North Waziristan on Friday, killing five government soldiers about two miles from the scene of a U.S. missile attack that had killed a top al-Qaeda commander, officials said.

Eight other soldiers were wounded in Friday's attack, a military spokesman said. The suicide bombing broke a unilateral cease-fire declared by militants in the area a couple of months ago.
It was unclear whether the attack in retaliation for the missile strike against Abu Laith al-Libi, whose death was reported Thursday on websites and confirmed by an American official. The official said the al-Qaeda leader died when a missile from a U.S. Predator drone struck a compound in Pakistan's North Waziristan region late Monday.
The U.S. missile strike marked a significant victory for the U.S. in its battle against the terror network after a series of pessimistic assessments of the American-led campaign against the Taliban in neighboring Afghanistan.
A Pakistan government spokesman in Islamabad said he had no information to prove al-Libi was killed in the strike, which occurred near the town of Mir Ali. But Pakistani intelligence officials in Miran Shah, a main town in North Waziristan, said there were strong indications he died.
