On Monday, Russia apparently bombed three Syrian hospitals and a school.
"The Russian air campaign has grown both in terms of number of strikes and geographic reach," Michael Horowitz, a senior intelligence analyst at the Levantine Group responsible for Syria, told me.
These are areas where Syrian rebels, as well as the Syrian al-Qaeda franchise Jabhat al-Nusra, are battling Bashar al-Assad's forces.
"I think it all has to stop," Medvedev said, "when peace arrives." Civilians are, of course, bearing the brunt of this assault: Russia does not try very hard to avoid collateral damage.
But the gains, such as they are, are quite limited — and come at tremendous humanitarian cost.
According to observers of the Syria conflict, Russian bombing has escalated substantially since it began in September 2015 — particularly in the past few weeks.
The goal has been to help the Syrian government, which was until recently tottering, seize more territory in advance of the planned ceasefire (though it's far from clear that this ceasefire will actually materialize).
These bombings, in addition to being a humanitarian catastrophe, speak to Russia's growing offensive in Syria and the impact it is having on the war there. Bashar al-Assad's forces have reversed the war's momentum and even made real gains in some areas.
ISIS has no real presence there, and the group is the sole target of America's airstrikes.
Russia, instead, is striking areas held by Syrian rebels — and recently it's been picking up the pace.
There have also been strikes against rebel positions in south (near Daraa), as well as some targeting ISIS.
"Major air operations [have been] reported in northern Aleppo, in southern Syria and in eastern Aleppo (against ISIS)," Horowitz wrote.
