Leave war's mark in Afghanistan

Kabul is the capital of Afghanistan. There is military bases there. There is sad business in northern part of kabul. It's picking up metal. The metals are weapon's wreckages in war. Some person pike up the weapon and it exploded. It was unexploded bomb. The people lost or injured their arms or legs. Afghanistan has the many buried land mine and the many drained refugee. I think the government should remove the land mine.
