"In Mosul, we have cleared 47,000 different types of explosives and 2,000 of them are what we in Sweden would call terrorist bombs," says Pehr Lodhammar, head of the UN mines and ammunition smugglers in Iraq.
In addition, the UN is working to educate those who want to return, so that they become aware of the risks and learn to detect ammunition in the masses.
- The ammunition manufactured by IS is made from what you can find in a normal hardware store. Without education, they do not know what it looks like. I call it life saving messages, he says.
