REPUBLIKA.CO.ID, NEW YORK -- Another UN peacekeeping contingent serving in the Central African Republic is suspected of sexually abusing street children in Bangui, a UN spokesman said Tuesday.

It was the third case of alleged child sexual abuse involving peacekeepers in that country to have surfaced in recent months.

The UN mission in Bangui has notified the troop-contributing country of the new allegations and has opened an investigation, said Stephane Dujarric.

The country of origin was not identified, but a UN official said it was an African contingent.
