Over 200 civilians have died since Russia launched air strikes in Syria, a report by Amnesty International says.
The human rights group says it "researched remotely" more than 25 Russian attacks in five areas between 30 September and 29 November, and found "serious failures [by Russia] to respect international humanitarian law".
Amnesty said it researched Russian attacks in Homs, Hama, Idlib, Latakia and Aleppo, and "interviewed by phone or over the internet 16 witnesses to attacks and their aftermath", including doctors and human rights activists.
The group said it also "obtained and reviewed audiovisual imagery" relating to the attacks and "commissioned advice from weapons experts".
