KUWAIT CITY - A Kuwaiti soldier in an army bomb disposal unit was killed on Sunday while trying to defuse explosives left behind by Iraqi troops, an army spokesman said. The incident took place in northwestern Kuwait when an explosive device caught fire, badly burning the soldier who later died, Brigadier Yussef Al Mulla said in a statement quoted by the KUNA news agency.Iraqi troops under orders from ousted President Saddam Hussein occupied Kuwait in August 1990 before they were evicted seven months later by a US-led coalition. They left behind large quantities of unexploded landmines and ordnance which have killed dozens of Kuwaitis and foreigners.
