The Syrian army and its allies announced the capture of a swathe of eastern Aleppo from rebels on Monday in an accelerating attack that threatens to crush the opposition in its most important urban stronghold.
Norbert Roettgen, a lawmaker in Merkel's Christian Democratic (CDU) party, and Greens parliamentarian Franziska Brantner said that the West must act immediately in view of the Syrian-Russian attacks in eastern Aleppo.
