As the violence in Syria continued to go from bad to worse in scope and intensity, US official sources had this to say Saturday, June 16, about planned US military operations in the war-torn country:

“The intervention will happen. It is not a question of ‘if’ but ‘when.’”

A Syrian Free Army rebel delegation is now in Washington to talk about their requests for heavy weapons from the Obama administration.

In their meetings with US Ambassador to Syria Robert Ford and the State Department’s expert on Syria Fred Hof, the rebel leaders handed in two lists for approval: types of heavy weapons capable of challenging Bashar Assad’s armed forces and selected targets of attack to destabilize his regime.

DEBKAfile’s Washington sources disclose that the administration is very near a decision on the types of weapons to be shipped to the Syrian rebels and when. Most of the items Washington is ready to send have been purchased by Saudi Arabia and Qatar and are ready for shipment.

The White House is also close to deciding on the format of its military operation in Syria. Some sources are defining it as “Libya lite” – that is, a reduced-scale version of the no-fly zone imposed on Libya two years ago and the direct air and other strikes which toppled the Qaddafi regime.

Following reports of approaching US military intervention in Syria and a Russian marine contingent heading for Tartus port, the UN observer mission in Syria has suspended operations and patrols. Its commander Maj. Gen. Robert Mood said, “Violence has been intensifying over the past 10 days by both parties with losses and significant risks to our observers.”

He said the risk is approaching an unacceptable level and could prompt the 300 observers to pull out of the country. Friday, June 15, DEBKAfile reported:

A contingent of Russian special forces is on its way to Syria to guard the Russian navy’s deep-water port at the Syria’s Mediterranean coastal town of Tartus, Pentagon officials informed US NBC TV Friday, June 15. They are coming by ship. According to DEBKAfile’s sources, the contingent is made up of naval marines and is due to land in Syria in the coming hours.

In a separate and earlier announcement, US Defense Department sources in Washington reported that the US military had completed its own planning for a variety of US operations against Syria, or for assisting neighboring countries in the event action was ordered – a reference, according to our sources, to Turkey, Jordan and Israel.

The Syrian civil war is now moving into a new phase of major power military intervention, say DEBKAfile’s military sources. Moscow, by sending troops to Syria without UN Security Council approval, has set a precedent for the United States, the European Union and Arab governments to follow. They all held back from sending troops to Syria because all motions to apply force for halting the bloodshed in Syria were blocked in the UN body by Russia and China.

According to US military sources, in recent weeks, the Pentagon has finalized its assessment of what types of units would be needed and how many troops. The military planning includes a scenario for a no- fly zone as well as protecting chemical and biological sites. The U.S. Navy is maintaining a presence of three surface combatants and a submarine in the eastern Mediterranean to conduct electronic surveillance and reconnaissance on the Syrian regime, a senior Pentagon official said.
