DERA ISMAIL KHAN/PESHAWAR, Pakistan (Reuters) - At least 20 Pakistani soldiers were killed on Sunday when an explosion hit an army convoy in the northwestern town Bannu, intelligence and military sources said.
More than 30 others were wounded in the attack on the convoy as it prepared to leave the town at the gateway to North Waziristan, a lawless, tribal region on the Afghan border where many militant groups are holed up.
