In another sign of increasing friction between the USA -led coalition and the force backing President Bashar Assad, a US strike fighter shot down an unmanned "armed pro-regime" combat drone after it "displayed hostile intent" in southern Syria on Tuesday, the Pentagon said.
A US F-15E fighter downed an armed Iranian drone near Al-Tanf in Syria, where the United States is training Syrian rebels fighting against ISIS.
The drone was identified as a Shaheed-129 that displayed "hostile intent and advanced" on coalition forces at the At Tanf combat outpost used to train partner Syrian forces in the fight against the Islamic State (ISIS).
Murphy's remarks came two days after a U.S. Navy fighter jet shot down a Syrian warplane for the first time, prompting Russian Federation to issue a threat against American airborne assets over Syrian airspace.
Russian Federation on Monday said that it was closing the communication line after a U.S. F-18 Super Hornet downed a Syrian government SU-22 fighter-bomber on Sunday. The Russian defense ministry's statement added that any coalition aircraft flying west of the Euphrates River would be tracked and "considered air targets".
As a result, it said, Russia has stopped using a key "de-confliction" communication channel set up to avoid conflict between US and Russian forces in Syria.
The U.S. has maintained its broadening military involvement in Syria is part of the global fight against ISIS, and has avoided engaging directly with the regime of Syrian President Bashar Assad and the larger civil war playing out in Syria. He also noted the shoot down of the Syrian jet was legal under the 2001 authorization Congress passed for the us military to target al Qaeda.
Russian Federation and Iran both support Syrian President Bashar al-Assad in Syria's civil war.
In a statement, the Defense Ministry said operations had been "temporarily ceased" as a "precautionary measure" but would be resumed in "due course". USA warplanes launched three other airstrikes against the forces there.
Fighting and bombardment meanwhile resumed early Tuesday between Syrian government forces and rebels in the southern city of Daraa and nearby areas, where a 48-hour truce had gone into effect on Saturday.
BEIRUT (AP) - Syrian government troops and their allies have steadily positioned themselves in key areas on the flanks of the US -led coalition battle for the Islamic State's self-declared capital of Raqqa.
Meanwhile the Syrian army and its allies are also closing in on Raqqa and last week the Syrian military reached areas controlled by the SDF, making clashes between the opposing alliances nearly inevitable.
Such targets would be US planes and surveillance drones. Israeli security officials said on Monday they were studying the missile strike to see what they could learn about its accuracy and capabilities.
Georgia voters steadily streamed into suburban Atlanta polling places Tuesday to decide the most expensive House race in US history and put weeks of television ads, phone calls and ringing doorbells behind them.
"It's that fighting spirit, that perseverance and tenacity that I will take to Washington", she said Tuesday night.
Tensions escalated on Sunday as the US Army brought down the jet near Raqqa and Iran launched missiles at IS targets in eastern Syria - the first time each state has carried out such actions in the multi-sided Syrian war.
