Russia Threatens to Begin Targeting American Aircraft

While the USA has said since it began recruiting, training and advising what it calls moderate Syrian opposition forces to fight IS that it would protect them from potential Syrian government retribution, this was the first time it resorted to engaging in air-to-air combat to make good on that promise.

On June 18, American armed forces shot down a Syrian warplane after reportedly seeing the jet drop bombs near a USA -backed coalition group that had been fighting an ISIS unit.

"The Coalition's mission is to defeat ISIS in Iraq and Syria", the Pentagon added. Col. Ryan Dillon told the NYT, "We are going to continue to conduct operations throughout Syria, providing air support for coalition and partnered forces on the ground".

"In this regard, the threat of direct confrontation between the aviation of Russia and the U.S. does not arise", the Federation Council's Committee on Defence and Security chairman said".

MOSCOW (AP) - A top Russian diplomat on Monday condemned the United States for shooting down a Syrian Air Force fighter jet the previous day as an act of "aggression", while USA -backed opposition forces on the ground warned Syrian government troops to stop their attacks or face retaliation. -Russian military "deconfliction" hotline in response to a US shootdown Sunday of a Syrian fighter jet.

The deconfliction arrangement - first established with Russian Federation in 2015 to avoid mid-air collisions in Syria as both sides fight militant groups - was broken after a U.S. Navy F/A-18E Super Hornet on Sunday shot down a Syrian warplane in the southern part of the Islamic State in Iraq and Syria's (ISIS) stronghold in Syria.

Russia's defence ministry condemned the downing of the jet in a separate statement, saying the latest incident, in addition to others, was a violation of worldwide law.

A US F/A-18 took off from the USS George H.W. Bush in the Mediterranean on Sunday and shot down a Syrian Su-22 the USA said had dropped bombs near US-backed forces.

Analysts say neither Washington nor President Bashar al-Assad's regime appear to be seeking further confrontation, but warn the risks are high in Syria's increasingly crowded battlefields.

The announcement comes after an American jet shot down a Syrian jet on Sunday.

Frants Klintsevich, the deputy chairman of the Russian Senate's defense committee, said the attack was a "blunt act of aggression and provocation".

"The Syrian regime ... needs to understand that we will keep the right of self-defense of coalition forces aligned against ISIS", he said.

Joseph Dunford, chairman of the Joint Chiefs of Staff, suggested that broader USA and Russian interests will enable to the two sides to avoid direct hostilities in Syria.

Russian defense ministry said it will suspend an agreement between the USA and Russia that worked to limit the risk of in-flight incidents between the two countries, The Washington Post reported.

Dunford said he is focused on ensuring the USA can achieve its main goal in Syria - the defeat of Islamic State militants.

Russia's defense ministry says it is suspending coordination with the United States in Syria over so-called "de-confliction zones" after the Americans downed a Syrian government fighter jet.
