At least three security personnel were killed and three others injured when a bomb went off near an army vehicle in Pakistan's Northwest tribal area, officials said. The Inter Services Public Relations (ISPR), the mouth piece of Pakistan army, said in a statement that an army vehicle was hit by a roadside planted device at the bordering area of North Waziristan and South Waziristan agency on Sunday night, Xinhua reported. The injured troops were shifted to a nearby hospital for medical treatment. The vehicle was completely destroyed in the blast. No group has claimed responsibility for the attack yet. Sunday night's incident is a continuation of the recent string of terrorist attacks at army and police vehicles following the end of peace talks between the Pakistani government and Taliban. The recent attacks have left over a dozen policemen and troops killed, and at least 50 injured in the country's Northwest Khyber Pakhtunkhwa, South Sindh and Southwest Balochistan provinces over the last one week.
