Pakistan Mourns School Massacre Dead

Flags are flying at half-mast across Pakistan, as the nation marks three days of mourning for the 141 people, most of them children, killed in a brazen attack on a school in the northwestern city of Peshawar. Prime Minister Nawaz Sharif called a multi-party conference in Peshawar on Wednesday to discuss the state response to the attack, the worst in Pakistan's recent history, which will be attended by leaders across the political spectrum.
