AMMAN (Reuters) – Syrian state media said on Sunday government forces had seized most of rebel-held Aleppo province in another major gain by a Russian-backed offensive.

Russian warplanes mounted heavy air strikes in the area on Sunday, bombing towns including Anadan, which was later seized by Syrian government forces backed by Iranian-backed militias, activists reported.
