Fighters from Sudan’s Rapid Support Forces and the Central African Republic’s former Seleka rebels on Tuesday attacked a UN base near the Sudan border wounding three Zambian peacekeepers.

The UN Mission in the Central African Republic (MINUSCA) “strongly condemned” the dawn raid in the town of Am Dafock targeting one of its bases in the impoverished, volatile nation.

It said three Zambian peacekeepers were wounded, one of them seriously.

Valentine Rugwabiza, Special Representative of the UN Secretary-General, said the attacks on the blue helmets “may constitute war crimes under international law”.

Ramadan Abdelkader, the sub-prefect of Am Dafock, told AFP: “Former Seleka fighters and elements of the Rapid Support Forces (RSF) coming from Sudan attacked the bases,” adding that 22 people had died.
