"Rounding up illegal weapons"
US Marines are taking part in an effort to collect illegal weapons in Haiti.
The US-led multi-national force in Haiti is to begin rounding up illegal weapons in an effort to restore order and end weeks of violence.
US marines said an operation with Haitian police to take weapons from armed groups would start on Wednesday.
Foreign troops arrived in Haiti more than a week ago after President Jean-Bertrand Aristide left the country.
A new prime minister, Gerard Latortue, has been appointed in a bid to fill Haiti's political vacuum.
The move to disarm rebel groups comes as a United Nations mission of political, military, police and logistics experts is expected to arrive in Haiti.
The mission is intended to pave the way for a UN peacekeeping force to be deployed within three months.
