Militants must be "cleaned out" of Syria's Idlib, Iran says

Turkey, which has long supported anti-Assad rebels, has cooperated with Russia and Iran on talks

(Reuters) - Iran called on Monday for militants to be "cleaned out" of Syria s Idlib province, as it prepared for talks with Syria and Russia about confronting the last major enclave held by rebels opposed to President Bashar al-Assad.

Syrian government forces are planning a phased offensive in Idlib and surrounding areas held by insurgents fighting Assad, who has been backed by both Russian and Iranian forces in the country s conflict.

US Secretary of State Mike Pompeo has said Washington views any government assault on Idlib as an escalation of Syria s war, and the State Department warned that Washington would respond to any chemical attack by Damascus.

Iranian Foreign Minister Mohammad Javad Zarif visited Damascus to discuss plans for an upcoming summit between the leaders of Iran, Russia and Turkey, which Tehran will host on Sept. 7 to discuss Idlib, Iran s Fars news agency reported.

Turkey, which has long supported anti-Assad rebels, has cooperated with Russia and Iran on talks over Syria in recent years and has troops in the Idlib region on an observation mission.

Zarif met Assad, Syrian Prime Minister Imad Khamis and Syrian Foreign Minister Walid al-Muallem, who asked for Iran to continue its support, according to Iran s Fars News.

"All of Syrian territory must be preserved and all the sects and groups should start the round of reconstruction as one collective and the displaced should return to their families," Zarif said, according to Fars News.

"And the remaining terrorists in the remaining parts of Idlib must be cleaned out and the region should be placed back under the control of the Syrian people."

Assad s office said in a statement: "The two sides asserted that the pressures from some Western states on Syria and Tehran will not deter the two countries from continuing to defend their principles."

Last week, Iran s defence minister travelled to Damascus and signed an agreement for defence cooperation between the two countries with his Syrian counterpart. Iranian foreign ministry spokesman Bahram Qassemi said Iran would continue its support for Syrian government forces in its battle in Idlib.

Zarif went to Sayeda Zeinab, a shrine south of Damascus revered by Shi ites, as his first stop on the trip, according to Fars News.
