A U.S.-based advocacy group that recently disclosed nearly 100 allegations of sexual abuse by international peacekeepers in Central African Republic says the United Nations has documented 41 additional cases.

U.N. spokesman Stephane Dujarric would not confirm the new allegations, saying U.N. investigators are being "careful and methodical" in interviewing victims and determining the number.

The U.N. said on March 31 that 108 alleged victims of sexual abuse have been interviewed in Kemo prefecture, east of the capital Bangui.

Dujarric told reporters Wednesday "I would not be surprised if that number goes up a bit."

AIDS-Free World, which campaigns to end sexual abuse and exploitation, said it received a leaked U.N. cable from April 7 saying the U.N. peacekeeping mission had documented 41 new cases.
