Twelve people were killed and 80 injured in violent protests yesterday against the killing of two men and two women in a night-time raid by foreign troops in northern Afghanistan.
Hundreds of demonstrators armed with spades and axes, and chanting "death to America", took to the streets of Taloqan, a normally peaceful town in Takhar province, and tried to storm a foreign military base.
Police and residents said the four people killed in the raid late on Tuesday night in Taloqan were civilians. Nato-led forces say they were armed insurgents.
The Afghan President, Hamid Karzai, demanded an explanation from General Petraeus, the US and Nato commander in Afghanistan. "Despite repeated warnings to prevent wayward operations by Nato troops, it seems such incidents have not been stopped," he said.
