THE level of danger between forces in Syria could be increased between Russia and United States after the recent decision by Moscow to send its most advanced fighter jet to Damascus.
Both countries namely US and Russian have deployed forces in Syria where as they support government and other opposition parties which want to remove out of power current president Assad.
CNN quoted a US military official saying that Russia has sent its most advanced fighter jet to Syria. It's a deployment that could potentially increase the level of danger to US forces operating inside the country.
The Su-57 is Moscow's most sophisticated military jet and comes equipped with stealth capability.
Russia's move comes despite a promise from President Vladimir Putin to scale back Russia's military commitment in the country.
"The addition of fifth-generation fighters into Syria would certainly not be in keeping with Russia's announced force drawdown," Pentagon spokesman Maj. Adrian Rankine-Galloway told newsmen.
The deployment comes on the heels of the United States employing its most advanced fighter jet, the F-22 stealth fighter, in strikes against targets in Syria after a February 7 assault against US-backed forces by pro-Syrian government troops that also included Russian mercenaries.
US officials estimate 500 pro-regime troops were involved in the attack on a complex where both US troops and their allies in the Syrian Democratic Forces were stationed.
In December, two F-22's intercepted two Russian aircraft that had flown east of the "de-confliction line" that is supposed to separate Russian and US-led coalition aircraft operating over Syria.
The US jets fired warning flares during the intercept of the two Russian Su-25 close air support jets, according to US officials, after they crossed the de-confliction line multiple times.
"We do not consider these jets to be a threat to our operations in Syria, and will continue to deconflict operations as necessary," Rankine-Galloway said.
The Russians have based the jet at their Khmeimim air base in Syria, according to the US military official.
