Members of the U.N. Security Council are visiting Burundi to try to help end political unrest that sparked deadly violence.

France, the U.S. and Angola are leading the 15-member council delegation that will be in Burundi until Friday.

The visit follows U.N. human rights chief Zeid Raad al-Hussein's report last week of gang rapes of women here by security forces, torture and signs of ethnic repression.

His office cited growing signs that Tutsis were being targeted in the Hutu-majority country that borders Rwanda, where a 1994 Hutu-led genocide targeted Tutsis and moderate Hutus.

President Pierre Nkurunziza's decision to seek re-election last April touched off street protests that led to a failed coup in May and a rebellion that has left the country on the brink of civil war.
