Russia launched airstrikes in support of the Syrian army Monday in an effort to stanch a major rebel advance that surprised and overwhelmed the forces of Syrian President Bashar al-Assad late last week.

After initially withdrawing from some areas, Syrian government forces appeared to be regrouping to counterattack Monday. The Syrian army said its warplanes also carried out airstrikes against the rebel forces that are posing the most significant challenge to Assad’s rule in more than a decade. And in the background, Iranian officials launched a diplomatic blitz to shore up the Assad regime.

Whether Syrian government forces can stop the lightning assault and roll back rebel gains will largely depend on how much support Russia and Iran provide the Assad regime. Both allies have been instrumental in helping Assad cling to power as the country was engulfed in a civil war that killed tens of thousands of civilians.
