Protests are continuing in Afghanistan for a fifth day in a row over the killing of civilians by U.S. troops. Afghan officials say over 50 civilians have been killed in raids by U.S.-led troops against the Taliban in the past week. In the city of Nangarhar 2,000 students rallied on Wednesday. The students burned and stomped on U.S. flags and chanted “Death to America.” One of the protesters, Jamaludding Khan, called for U.S. troops to leave Afghanistan.

Jamaludding Khan: “As the foreign troops failed to bring security to Afghanistan, we want them to leave Afghanistan as soon as possible, without any preconditions. If they do not take our demand seriously, we will continue our protest.”

Protesters have also called for the removal of the U.S.-backed Afghan president, Hamid Karzai. Karzai said that Afghans no longer have patience for the killing of civilians by Western forces hunting the Taliban.

Hamid Karzai: “Unfortunately, the suffering of Afghanistan in certain parts of the country has not ended. We still suffer, either by the operation of terrorists or in the consequence of operations by NATO. We still keep losing our civilian lives.”

Meanwhile, one of Afghanistan’s former prime ministers was shot and killed outside his home in Kabul on Wednesday. Abdul Saboor Farid briefly served as prime minister 15 years ago. He had been serving in Afghanistan’s upper house of parliament.
