Hours after Syrian President Bashar al-Assad fled the country following the invasion of Damascus by rebels, reports say he is now in Moscow, Russia.

A coalition of rebel groups led by the Islamist group linked to al-Qaeda began its latest offensive against Syrian government forces about seven days ago.

President Joe Biden said that the United States would engage with “all Syrian groups” over the political transition in Syria, describing Assad’s fall from power as a “moment of historic opportunity” for Syria.
