Saudi Arabia says the United States has welcomed Riyadh’s offer to contribute troops to a potential ground incursion by a US-led coalition in Syria.

Saudi Foreign Minister Adel al-Jubeir said the offer, made last Thursday, had been met with Washington’s approval and that Saudi forces would be playing a major role in any such operation.

“The United States government was very supportive and very positive about the kingdom’s readiness to provide special forces to the operation in Syria, should the international coalition make a decision to do so,” he told reporters.

“So the kingdom will be part of it,” he said. “That support came from the White House, it came from the [US] State Department, it was natural for [US] Secretary [of State John] Kerry to support such a decision.”

The 65-member coalition, of which Saudi Arabia is a member, has been conducting air raids inside Syria since September 2014. The airstrikes have no authorization from the Syrian government or the UN and have reportedly fallen short of uprooting the militants.

State Department spokesman John Kirby confirmed that the United States had welcomed the Saudi offer, but he would not comment on the nature or timing of any potential ground operation.

“We are talking about a ground element,” he said. “We have discussed the potential value of a special operations capability inside that element, which would be valuable.”

Washington itself has deployed special forces to eastern Syria in what it claims is an effort to shore up local militias against Daesh.

Reacting to a potential troop deployment, Syrian Foreign Minister Walid al-Muallem said Saturday, “Let no one think they can attack Syria or violate its sovereignty because I assure you any aggressor will return to their country in a wooden coffin.”

Russia has been conducting airstrikes against Daesh, al-Qaeda-linked al-Nusra Front and other terrorist targets at Damascus’ request since last September.

A top Iranian military commander has dismissed Saudi plans as a "bluff," saying the kingdom would face a "definite" defeat in Syria if it sent troops there.

“Sending troops by Saudi Arabia would mean a coup de grace for its regime which, of course, is not bad,” chief commander of the Islamic Revolution Guards Corps Major General Mohammad Ali Ja’afari said on Saturday.
