Mr Fidan separately met the head of Sudan's ruling Sovereign Council Lt Gen Abdel Fattah al-Burhan and his deputy, Lt General Mohammed Hamdan Dagalo (Hemeti).

Both meetings were attended by Sudan's spy chief Lt Gen Ahmed Ibrahim Mufadal, Sudan TV said

Mr Fidan conveyed his country's support for the framework agreement the military leaders signed with some pro-democracy groups on 5 December.

Turkey was among members of the international community that backed the deal, which was meant to pave the way for the return of civilian rule in Sudan.

However, pro-military and Islamist groups have opposed the deal.
