ISLAMABAD (Agencies) - Food aid distribution centres were closed temporarily in north-west Pakistan following a suicide bombing that killed 45 people outside a World Food Programme depot, an official has said. Shafiq Khan, an official involved in the World Food Programme food distribution project, said the four relief centres in the Bajaur district have been shuttered after the Khyber Pakhtunkhwa government ordered their temporary closure following Saturdays attack in the main town of Khar, which killed 45 people and injured over 100. It was not immediately clear how long the food distribution points would be closed.
