In response to the humanitarian crisis, the US tried to station unarmed aid workers in northern Iraq, but the Kurds refused to return. The US, the UK, France, the Netherlands, and Turkey then created a safe area between the cities of Amadiya, Dihok, and Zakho, and excluded the Iraqi military and police from the area. Near Zakho, the US military built a tent city to hold refugees, but it was not extensively used. The Kurds eventually moved to the safe area.
