Foreign Minister Mevlüt Çavuşoğlu has called for Russian airstrikes to be halted and a swift delivery of humanitarian aid to Aleppo.
Speaking after a meeting in Riyadh with his Saudi counterpart on Thursday, Çavuşoğlu reiterated that Turkey wants Mosul residents to liberate city from Daish without including the help of terrorist group PYD/YPG.
Çavuşoğlu also held a meeting with his counterparts from the six-nation Gulf Cooperation Council (GCC).
"Ministers condemned the escalation of military operations in Aleppo by the regime and its supporters through indiscriminate air raids against the civilian population and infrastructure," in a statement issued at the end of the GCC-Turkey talks.
New Zealand, one of the 10 non-permanent UN Security Council members, on Wednesday presented a draft resolution demanding an end to air attacks in Aleppo.
The measure followed the failure of the council to adopt two resolutions on a ceasefire in Syria, one of which was vetoed by Russia during a stormy meeting at the weekend.
Gulf ministers and their Turkish counterpart "expressed their deep regret for the inability of the UN Security Council to make a decision to stop the air campaign and the bombing of civilians in Aleppo", their statement said.
Russian and Syrian regime warplanes have been backing a large-scale offensive by Syrian regime forces against opposition-controlled east Aleppo.
More than 70 civilians died on Tuesday and Wednesday alone in air strikes and regime artillery fire on eastern Aleppo districts, a monitoring group said.
