Russian and Turkish foreign and defense ministers met in Moscow on Saturday to discuss northern Syria as U.S. forces prepare to withdraw and Turkey threatens to launch a military operation against U.S.-backed Kurdish forces controlling nearly a third of the country.

Russian Defense Minister Sergei Shoigu said before the talks began that they would focus on the situation in and around Idlib, as well as "what can and should be done" when the U.S. withdraws from Syria.

After the meeting, Russian Foreign Minister Sergei Lavrov told reporters that much of the discussion focused on the pending U.S. withdrawal, and that Russia and Turkey managed to agree on coordinating their steps in Syria "to ultimately eradicate the terrorist threat."

Turkey's official Anadolu news agency said the meeting lasted an hour and a half. Turkish Foreign Minister Mevlut Cavusoglu said only that "we will continue our close cooperation with Russia and Iran on Syria and regional issues."

The Syrian military said it entered the Kurdish stronghold of Manbij on Friday as part of an apparent agreement between the two sides. The Kurds are looking for new allies to protect against a threatened Turkish offensive as U.S. forces prepare to leave.

With President Donald Trump's surprise decision to withdraw troops earlier this month, Turkey announced it will pause a threatened offensive against Kurdish militants. It has, however, continued amassing troops at the border as it monitors the situation.

The movements follow days of equipment transfers across the border into a Turkish-held area of northern Syria near Manbij. Turkish-backed Syrian opposition fighters said they have started moving along with Turkish troops to front-line positions near the town as a show of readiness.

A statement released by the rebels said they are ready to "begin military operations to liberate the city in response to calls by our people in the city of Manbij."

Turkish news agency IHA showed video of at least 50 tanks arriving at a command post in Sanliurfa province early Saturday. The province borders Kurdish-held areas east of the Euphrates river in Syria.

The Russian side was represented in Saturday's talks by Foreign Minister Sergei Lavrov, Defense Minister Shoigu, and Kremlin foreign affairs aide Yuri Ushakov. The Turkish delegation includes Foreign Minister Mevlut Cavusoglu, presidential spokesman Ibrahim Kalin, intelligence chief Hakan Fidan and Defense Minister Hulusi Akar.

Kremlin spokesman Dmitry Peskov told reporters in Moscow on Saturday that, in addition to the foreign and defense ministers of each country, the meeting was attended by intelligence chiefs from both sides.

Presidents Vladimir Putin and Recep Erdogan did not attend the meeting. Peskov said the two would later schedule a separate meeting.
