PESHAWAR, Pakistan (AP) — A bomb ripped through a police van as it was patrolling in northwestern Pakistan on Monday, killing two officers and wounding two others, police said.
The attack took place on the outskirts of the city of Peshawar, which is located on the edge of Pakistan's tribal region, the main sanctuary for Taliban militants in the country. The city has been hit by frequent bombings over the past few years.
It's unclear if the blast was caused by a roadside bomb or a suicide bomber, said senior police officer Javed Khan. The bombing completely destroyed the police van that was hit, he said.
Also Monday, a gunman riding on a motorcycle killed the leader of an Islamic seminary in the southern city of Karachi, sparking a riot by hundreds of seminary students who stoned shops and set vehicles on fire, said police officer Azhar Iqbal.
Karachi has a long history of political, sectarian and ethnic strife, which has been on the rise this year.
