Russian jet in Syria
It's a bad time to be a "moderate" in Syria: Even the Washington Post is now reporting that Al-Nusra and other freedom-loving moderate groups are losing the war. As the SAA closes in on Aleppo, Russia is paving the way for a new offensive in northern Homs. And by "paving the way", we really mean "36 hours of continuous airstrikes":
For 36 straight hours, the Russian Air Force has pulverized the Islamist rebel defenses in northern Homs, as the Syrian Arab Army's 47th Brigade of the 11th Tank Division and the National Defense Forces (NDF) prepare to strike the imperative villages of Harbinifseh and Kisseen that are located along the Orontes River.

According to a senior officer from the Syrian Arab Army, the Russian Air Force's powerful airstrikes over northern Homs are part of the largest aerial campaign launched by the Russian Federation since the advent of their participation in the Syrian Conflict.
Trusted western media outlets are already crying foul, accusing Russia and Assad of derailing peace talks.

The reality is that the west and its Arab client states wanted terrorist groups to have a seat at the negotiating table, which was (rightfully) unacceptable to Moscow.

It looks like Russia has found a more effective way of negotiating with Al-Nusra and Ahrar Al-Sham: Surrender or be turned to dust.
