Libyan leader Moammar Gadhafi vowed to fight on to his "last drop of blood" and roared at his supporters to take to the streets against protesters demanding his ouster, shouting and pounding his fist in a furious speech Tuesday after two nights of a bloody crackdown in the capital trying to crush the uprising that has fragmented his regime.

It was the second time Gadhafi has appeared during the week of upheaval across his country. Swathed in brown robes and a turban, he spoke on state TV from behind a podium in the entrance of his bombed-out Tripoli residence hit by U.S. airstrikes in the 1980s and left unrepaired as a monument of defiance.

U.S. Senators John McCain and Joseph Lieberman stressed on Tuesday that Washington is watching to see whether Lebanon's future government will respect the findings of the Special Tribunal for Lebanon investigating the assassination of former Lebanese Prime Minister Rafik Hariri.

Lieberman said after meeting with Prime Minister-designate Najib Miqati that the U.S. State Department considers Hizbullah a terrorist organization and any role the party has in the new government will affect how the U.S. deals with it.

Raul Krauthausen, who has used a wheelchair since childhood, has always been uncomfortable with the services Germany provides for the physically handicapped, like special taxis and grocery delivery — saying they feel patronizing and further isolate him from the able-bodied world.

So Krauthausen took matters into his own hands and launched wheelmap.org, an iPhone application and website in German and English that allows users to share ratings and tips on how accessible shops, bars and other places are.

Cell phones are usually used to communicate with people far away. This year, they'll get the ability to do the opposite: communicate with things that are close enough to touch.

It may not sound immediately useful, but phones will get some surprising capabilities with the addition of chips for so-called Near Field Communications, a wireless technology with a range intentionally limited to just a few inches.

Deep rifts opened in Moammar Gadhafi's regime, with Libyan government officials at home and abroad resigning, air force pilots defecting and a bloody crackdown on protest in the capital of Tripoli, where cars and buildings were burned. Gadhafi went on state TV early Tuesday to attempt to show he was still in charge.

World leaders have expressed outrage at the "vicious forms of repression" used against the demonstrators.

Sappers in Russia's insurgency-plagued Caucasus region defused a car bomb placed near a hotel in a popular ski resort area, police said Sunday.

The car, wired with explosives with the equivalent power of about 70 kilograms (155 pounds), was found Saturday, a day after three Russian tourists headed for the ski area were killed by masked gunmen and a ski lift was heavily damaged in an explosion.

Israel's prime minister on Sunday accused Iran of trying to exploit the recent instability in Egypt by sending two warships through the Suez Canal into the Mediterranean, saying he views the move "with gravity."

The Iranian ships were expected to make a rare crossing through the canal on Sunday or Monday en route to Syria — an Iranian ally and Israel's enemy to the north. Egypt confirmed the ships would be allowed through the strategic passage.

Lonely astronauts on the International Space Station may soon be getting an android friend from Japan.

Almost 10,000 infants and toddlers are hurt in crib and playpen accidents each year, according to the first nationwide analysis of emergency room treatment for these injuries.

Most injuries were from falls in toddlers between ages 1 and 2 — generally old enough to attempt climbing out of a crib or playpen.

An anchored boat packed with sleeping tourists sank early Thursday in Vietnam's scenic Ha Long Bay, killing 12 people from nine countries in the deadliest tour boat accident since the country opened to foreign tourism 25 years ago.

Vacationers from the U.S., Britain, Australia, Japan, Russia, France, Sweden and Switzerland have been confirmed dead, along with a Vietnamese tour guide, the government said. Another nine foreigners and six locals were rescued by other tour boats in the bay's emerald waters.
