Suicide bomber detonates in North Waziristan, near border with Afghanistan . Three children aged four to 11 years old killed in the attack .

Officials in Pakistan's restive northwestern zone bordering Afghanistan said on Sunday that a suicide bomber killed three children and three soldiers in an attack on a military vehicle.The rugged border between Pakistan and Afghanistan has long been a hive of resistance, with fighters escaping the porous border with state security forces.On Saturday evening, a suicide bomber detonated in a small market near Miran Shah in North Waziristan, just 26 kilometers (16 miles) southeast of Afghanistan.Three children aged four to 11 years old were killed in the suicide attack on the heavily militarised area, according to Pakistan's army.

Killers of innocent children, according to Pakistan's prime minister Shehbaz Sharif, are infamous enemies of humanity and Islam.In a statement, he said, we won't sit in peace until we hunt down these barbarians and those who favor them.No terrorist groups have claimed responsibility for the assault.Tehreek-e-Taliban Pakistan (TTP), the Pakistani Taliban, has a long tradition of preparing attacks in the region.

However, a 2014 military offensive crushed the rebellion and led its remaining members across the border into Afghanistan, following the brutal massacre of nearly 150 schoolchildren in Peshawar.Islamabad has increasingly claimed that since the Afghan Taliban took power in Kabul, it is providing a safe haven to militants who launch assaults along its border.However, Saturday's explosion occurred in the midst of a cease-fire to facilitate peace negotiations.TTP leaders had warned fighters not to violate the central command's decision in a letter.

Both men died on the spot and the attackers fled from the scene, according to local police chief Muhammad Ijaz Khan.
