French President Francois Hollande hit out at Russia’s role in the ongoing siege of Aleppo, saying that Moscow had broken a promise to aid trapped civilians. “Russia is making commitments that it is not keeping. There’s a moment where you have to answer with action,” Hollande said as he arrived for an EU summit overshadowed by events in the besieged city where Syrian and Russian forces are forcing out rebels. Hollande warned that “if there lacks effort in the coming hours, the regimes that support al-Assad will take the responsibility for this extremely serious situation for the population.”
