A bomb exploded in a religious school in insurgency-hit southwestern Pakistan yesterday, killing five people, police said.
The bomb was planted inside a school 15km north of Quetta, capital of Baluchistan province.
"We have sent our teams to investigate the blast inside the school, which killed five students and wounded seven others," senior police official Wazir Khan Nasir told AFP.
Nobody has so far claimed responsibility for the explosion.
Tribal rebels in gas-rich Baluchistan, which borders Afghanistan and Iran, are waging an insurgency, demanding political autonomy and a greater share of profits from the region's natural resources.
Hundreds of people have died in violence in the province since the insurgency flared in late 2004.
The province has also been hit by attacks blamed on Taliban militants.
