Suicide Bomb Kills 15 in Pakistan

A suicide bomber, wearing a woman's burka, has killed at least 15 people in an attack at a bus police checkpoint in northwest Pakistan. Four policemen were among the dead and at least 20 people were injured in the blast in the garrison town of Bannu. The bomb was detonated in a rickshaw, which had been stopped for inspection. It is the latest in a series of deadly attacks blamed on Islamist militants in the North Waziristan tribal region near the border with Afghanistan.
