President Recep Tayyip Erdoğan called the new UN Secretary-General Antonio Guterres on Tuesday to request an emergency UN meeting on Aleppo.
Erdoğan discussed the dire humanitarian situation in the Syrian city of Aleppo.
Underlining the importance of UN action on the atrocities taking place in the besieged city of Aleppo, Erdoğan said that he expected the UN General Assembly to hold an emergency meeting on the matter.
The Turkish Foreign Ministry had earlier expressed its outrage and horror over civilian massacres in eastern Aleppo, calling for an immediate evacuation for civilians under the surveillance of the UN and allowing aid into the city.
Late Tuesday, all sides agreed on a ceasefire for the imminent evacuation of civilians and opposition fighters from east Aleppo after mediation efforts from Turkey.
Under the truce deal civilians and opposition fighters will be granted safe passage to Idlib, from which they will be free to relocate. Turkey and Russia will serve as guarantors for the agreement.
The president also congratulated Guterres on his appointment as the ninth U.N. chief in the body's 71-year history.
Guterres took on the position from Ban Ki-Moon who had served two 5-year terms.
