“What’s the air-to-air threat there for them?” asked the official, who called the development “troubling”.

The European Union, which is divided on the issue, is to hold emergency talks next week.

“We’re prepared to negotiate”, Kerry said at a news conference in London.

“We’re committed to try to do more and we’re looking at exactly what it will take to do more“, Kerry said, noting that the United States has already contributed Dollars 4.1 billion in assistance for the asylum seekers from Syria and other war-torn countries. Carter emphasized that the military talks should go on with parallel diplomatic talks. Defeating IS has become a critical necessity and the sole force fighting IS in Syria remains al-Assad’s regime; thus Russia’s decision to bolster it does not deserve to be questioned. It would hurt the non-ISIS rebels in Syria, but Reuters reports Arab states may end up filling the void left by the Americans.

Sources say Russian Federation has set up an air traffic control tower and transported prefabricated housing units for up to 1,000 personnel to an airfield serving the Syrian port of Latakia.

He added: “But the other part of the equation is Assad and how you resolve the fact that he is a magnet for foreign fighters to come to the region”. In spite of differences the U.S. , Syria, and Russian Federation have cooperated in the past. But Ahrar al Sham has closely cooperated with the al Qaeda affiliates on the battlefield even while engaging in a very public dispute with ISIS.

Hassan Mustafa, spokesman for the “Division 30” unit to which some of the rebels were deployed, confirmed to AFP that the group had entered Syria.

The four soldiers said they went to the military prosecutor’s office in Novorossiisk, demanding a check into the legitimacy of the orders given by their commanders – which didn’t exist on paper. Recent efforts have also included Saudi Arabia. “It requires a political solution”. It only wants the preservation of the Syrian regime. “We have to find a way forward on a political transition”. This Kurd policy is just one more conflict the Turks have with the Kurds and the USA who support the Kurds.

The analysis group captured another shot the following day, this time showing at least four Russian Su-27 fighter jets parked at the Latakia airbase. This belated acknowledgement that Russian Federation has a crucial role to play in the future direction of Syria due to its longstanding relationship and therefore must be included in the process is a step in the right direction.

Washington and its North Atlantic Treaty Organisation allies broke off ties with the Russian military in April a year ago in protest at Moscow’s intervention in Ukraine. But working with Russian Federation on these aims presents a dilemma. We in the West have been pretending there is an alternative between IS and Assad despite there being no evidence of that.
