2 children wounded in grenade blast in Pakistan

Two children were injured today when a hand grenade exploded in a school in Pakistan's northwestern city here, officials said.
The incident occurred at Government Primary School for Boys Salam Baikay in Doogdara Upper District of Khyber Pakthunkhwa province which borders Afghanistan. Taliban has been active in the region.
The grenade exploded in the school ground shortly before the assembly. The school has no security or the boundary wall, officials said, adding that the grenade was planted in the school.
"We have told them many a time to construct the boundary wall and improve security measures but in vain," the district top administrators said.

One of the students sustained serious injuries, officials said.
Militants have destroyed hundreds of schools in the northwestern part of the country.
Pakistan suffered the deadliest extremist attack on a school here in 2014 that left more than 150 people, mostly children, dead.
