The United Nations says it has confirmed four new allegations of sexual abuse and exploitation against minors by U.N. peacekeepers in Central African Republic.

Deputy spokesman Farhan Haq said Tuesday the allegations involved peacekeepers from Congo.

The U.N. has already announced that a Congolese battalion in Bambari is being sent home, starting on Feb. 25, because of previous allegations of sexual abuse and exploitation.

The United Nations has been unable to explain why so many rapes and other sexual abuse by peacekeepers have been alleged in Central African Republic, which has been gripped by deadly violence between Christians and Muslims since late 2013.

Haq says Congo has 10 days to decide whether to investigate the latest allegations and if it doesn't, the UN will.
