Russia, Iran and Turkiye are in “close contact” over the conflict in Syria, Moscow said Wednesday, after a shock offensive has seen opposition fighters capture the second-largest city of Aleppo.

Axar.az reports that citing AFP, “The foreign ministers of the three guarantor countries – Russia, Iran and Turkiye – are in close contact with each other,” Russian foreign ministry spokeswoman Maria Zakharova told reporters on Wednesday.

Zakharova said Russia was “actively working with international partners to ensure the rapid stabilisation of the situation in Syria.”

In a phone call on Tuesday, Russian President Vladimir Putin told Turkish President Recep Tayyip Erdogan that the conflict needed a “speedy end,” and condemned “terrorist aggression against the Syrian state.”

A senior official from the office of Iran’s supreme leader was also in Moscow for talks on Wednesday, the Iranian Embassy said in a statement.
