More than 40 Afghan civilians have been killed in a string of deadly attacks. At least 19 people were killed Thursday when suicide bombers hit government buildings in the southern Afghan province of Uruzgan. The dead included 12 young children. Another 35 people were wounded. It was the deadliest attack to hit southern Afghanistan in nearly six months. Meanwhile, at least 23 civilians have been killed in a pair of roadside bombings. Nineteen people were killed when their bus struck a mine, while another four people died in a similar incident aboard a tractor. Afghan civilians are enduring record levels of violence, with more than 1,400 killed this year.
