KABUL, Dec 7, (Xinhua): Three workers were killed when an unexploded device left over from past wars went off in eastern Afghanistan's Nangarhar province on Saturday, provincial police spokesman Sayed Tayeb Hamad said Sunday. The incident occurred in a scrap shop in Kama district when workers were busy at the site on Saturday afternoon, the spokesman said, adding that three workers died on the spot due to the blast.

Police have urged residents to inform security authorities if they see or come across any suspicious objects. Earlier in November, a similar incident claimed one life in the Rodat district of Nangarhar province. Post-war Afghanistan has been regarded as one of the most mine-contaminated countries in the world, and the unexploded ordnances, which were left over from more than four decades of wars and civil unrest, often kill or maim people, mostly children, in the country.
