ISLAMABAD, Pakistan — Militants struck at the heart of Pakistan's security establishment Saturday, killing up to 35 people in suicide attacks on a checkpoint outside army headquarters and a bus carrying intelligence agency employees, officials said.

The two suicide attackers struck just before 8 a.m. in Rawalpindi as employees were arriving for work. In the first attack, an explosive-laden car rammed a bus carrying employees from the Inter-Services Intelligence agency. The other bomber hit an army checkpoint elsewhere.

SYDNEY, Australia — Labor Party leader Kevin Rudd swept to power in Australian elections Saturday, ending an 11-year conservative era and promising major changes to policies on global warming and the Iraq war.The win handed a humiliating end to the career of outgoing Prime Minister John Howard, who became Australia's second-longest serving leader — and who had appeared almost unassailable as little as a year ago."My fellow Australians, a few moments ago I telephoned Kevin Rudd and I congratulated him and the Australian Labor Party on a very emphatic victory," Howard said in Sydney in a nationally televised address. "This is a great democracy and I want to wish Mr. Rudd well."

BEIRUT, Lebanon — Lebanon awoke a republic without a president Saturday amid mounting worries over a power vacuum that has intensified the nation's yearlong political turmoil.The capital was calm and shops opened for business after a tumultuous day that saw President Emile Lahoud depart without a successor after announcing he was handing over security powers to the army. Lahoud's final announcement saying the country is in a "state of emergency" was rejected by the rival, pro-Western Cabinet of Prime Minister Fuad Saniora.The government rejection created fresh confusion in an already unsettled situation, which many Lebanese fear could explode into violence between supporters of Saniora's government and the pro-Syria opposition led by the Shiite group Hezbollah.Hezbollah and other opposition groups have blocked legislators from electing a new president by boycotting ballot sessions.
