A 10-year-old boy was killed and four others were wounded when an explosive apparently hidden inside a toy they were playing with detonated in Nowshera on Thursday, police said. The incident took place in Khaki, a suburb of Nowshera town in the Khyber-Pakhtunkhwa district, where many Afghan refugees are settled. "Up to six children were playing with a toy that they had found from the garbage they collected from nearby areas when it exploded, killing the boy and wounding four other children," senior local police official Khurram Rasheed told AFP.
