LANDI KOTAL, Jan 24: A security man was killed and two persons were injured when a bomb, buried under the debris of a destroyed school, went off in Landi Kotal tehsil of Khyber Agency on Tuesday.

During the inspection of the damaged building, an unexploded device buried under the debris went off, injuring three men including two khasadars.

Two rooms, a veranda and a portion of the boundary wall were damaged in the explosion. Nobody was present in the building at the time of the explosion as schools in Landi Kotal have been closed for winter vacations.

Officials said that they registered a case and started investigations. No one has so far claimed responsibility for targeting the school. The incident is second of its type in Landi Kotal in less than a week.

Officials of the education department said that number of schools destroyed in Khyber Agency had reached 57. Out of these schools 32 were targeted in Bara, 22 in Landi Kotal and four in Jamrud, depriving 16,000 children of education only in Bara tehsil.
