MOSCOW (Reuters) - Russia is preparing to resume air strikes around the Syrian city of Aleppo “in coming hours”, the Interfax news agency cited a source in the Russian Defence Ministry as saying on Tuesday.

The Kremlin said on Monday Russia’s air force would maintain a moratorium on strikes in Aleppo unless militants launched an offensive.
