Militant s kill 5 in Pakistan

Islamist militants have attacked a US based Christian aid agency in Pakistan, killing five people.

Police say gunmen burst into the World Vision agency in Mansehra district on Wednesday morning, where they set off a bomb and then opened fire.

Police exchanged fire with the attackers and are still searching for the suspects. The World Vision has closed all of its six offices across Pakistan due to the attack.

The UN and other aid agencies have been forced to limit their operations and the movement of foreign staff due to security threats.

The organization works in Pakistan to assist children affected by the 2005 earthquake which left thousands orphaned.
