KABUL, Afghanistan — Hundreds of Afghan and coalition troops took up positions around the Afghan capital today to prevent further anti-American riots a day after a deadly traffic accident set off the worst violence in the capital since the fall of the Taliban in 2001.

The city of 4 million was calm as stores reopened and residents commuted to work. Many expressed dismay as they surveyed the damage from Monday's riots.

"Where were all the security forces yesterday?" asked Asadullah Chelsea, who owns a supermarket popular with foreigners. "I have lost thousands of dollars of stock."

Meanwhile, the death toll from the unrest rose to at least 11, most of them from gunshot wounds, according to three city hospitals where casualties were taken. Kabul Emergency Hospital said it had 66 wounded, all shot. Dozens of other wounded residents were at other hospitals.

Chanting "Death to America," rioters stoned the U.S. convoy involved in the accident then headed to the center of Kabul, ransacking offices of international aid groups and searching for foreigners. Smoke billowed from burning buildings along the path of destruction.

The violence erupted after a mechanical malfunction sent a large cargo truck careening into about a dozen vehicles at an intersection in Kabul, the U.S. military said. Up to five people were killed in the crash. It wasn't clear whether these deaths were in the tolls the hospitals reported.

The rioters claimed U.S. troops had shot and killed civilians at the scene of the accident.

BANTUL, Indonesia — Two U.S. military cargo planes landed today at the site of an earthquake in Indonesia that killed more than 5,400, bringing some of the first significant aid to reach the tens of thousands of survivors who were left homeless.About 20 Marines arrived on the cargo planes in the historic city of Yogyakarta and unloaded heavy lifting machinery and a portable field hospital, as Malaysian, Chinese and Japanese rescue workers joined Indonesian teams providing medical care and emergency supplies to victims.Most of the survivors of Saturday's 6.3-magnitude quake were living in improvised shacks near the ruins of their homes or in shelters erected in rice fields. Officials say about 200,000 people lost their homes.However, conditions had improved in two hospitals in the quake zone, with no patients being treated outside or in the corridors today, like there were until recently.
