President Obama backed NATO's decision on Saturday to remove all foreign ministries from Afghanistan after two U.S. military officers were reportedly attacked and killed Saturday inside the heavily guarded Interior Ministry in Kabul, and government offices were put on lockdown as a result. NATO Gen. John Allen said they were being pulled for "obvious security reasons." Protests against the Quran burnings by NATO forces continued for a fifth straight day. Four people were shot dead by Afghan security forces, while another 50 were wounded in the normally restive northern Kunduz province, where hundreds of protesters tried to overrun a compound housing the U.N. Assistance Mission. The protesters were held back by police, an Interior Minister said. At least 28 people have been killed and hundreds more wounded since the protests began Tuesday.
