The ousted president of the Central African Republic, Francois Bozize, has accused neighbouring Chad of supporting the rebels who led a coup against him.
Bozize told the BBC that it was Chadian Special Forces who led the offensive and were involved in the attack on South African soldiers, which left 13 troops dead.
"On Saturday March 23 we had neutralised Seleka forces but overnight into Sunday 24, we knew that there had been support from an African country, which I inevitably believe was Chad," Mr Bozize told the BBC.
"We can confirm it was Chadian special forces that led the operation on the Sunday morning and attacked the barracks of the South Africans,
"To avoid a bloodshed I decided to resign after a phone call I made to the French ambassador,
"We had a solid and friendship relation with the Chadian authorities. Chad alone can give an explanation."
