KANDAHAR, Afghanistan–-- Afghans burned tires and chanted “Death to America” after U.S troops fired Monday(April 12, 2010) on a civilian bus near Kandahar, killing four people and wounding more than a dozen. Afghanistan’s president accused NATO of breaking its commitment to safeguard civilian lives.

The attack angered Afghan officials and the public in Kandahar, the Taliban’s birthplace, and dealt a blow to U.S and NATO efforts to win popular support for a coming offensive to drive the insurgents(叛乱分子) from the biggest city in the south. NATO expressed regret for the loss of civilian lives and said it was investigating.

Nearly 200 Afghans blocked highway where the shooting occurred, burning tires, firing weapons and chanting “Death to America” and other slogans. They also called for the ouster (forcing somebody out of a pasition) of Afghan President Hamid Karzai, a Kandahar native who has been appealing for the people here to support the U.S-led campaign against the Taliban.

“The Americans are constantly killing our civilians and the government is not demanding an explanation,” protester Mohammad Razaq said. “We demand justice from the Karzai government and the punishment of those soldiers responsible.”

Kandahar, a city of about a half million people, is nominally under government control, but the Taliban have stepped up infiltration(浸润), staging attacks and threatening local people.

“These foreigners have their enemies, but killing Afghans is not the answer,” said Abdul Hadi, who sells homemade herbal medicine in a public market. He said international forces should publish a schedule of their patrols(巡逻) so Afghans can keep out of the way.

“Better yet, I would like to see them leave Afghanistan,” he added.

Haji Zahir, who runs a transport firm, said it was time for U.S. and other foreign forces to withdraw from the country.

“They say they want to bring security. It is all lies, lies. They kill Afghans. That is not the way to bring security,” Zahir said.
