Chad: Chad steps up security at UN camps after three refugees are killed

Chadian authorities are tightening security in and around 10 United Nations refugee camps in the east of the country - where more than 200,000 Sudanese people have gathered after fleeing violence in the Darfur region - after three refugees were killed there in the past week amid rising tensions with locals. Some 180 Chadian gendarmes have started patrols around the camps and the UN High Commissioner for Refugees has handed over nine vehicles for the gendarmes to use.
