Members of the Iraqi Mine and Unexploded Ordnance Clearance Organization (IMCO) work with a sniffer dog to find mines in the Shatt-al-Arab district, in Iraq's southern city of Basra, November 6, 2012. Decades of war have left Iraq with one of the worst mine problems in the world, according to UNICEF, with around 20 million anti-personnel mines and more than 50 million cluster bombs believed to be left over in border areas and southern oilfields. Iraq's Environment Ministry says there are 25 million landmines scattered around the country, many along the border with Iran, a legacy of the war between neighbours that killed a million people.
