Russian President Vladimir Putin has suggested he is ready for a halt in fighting but says "there are nuances" - which he laid out talks with US envoy Steve Witkoff at the Kremlin on Thursday.

The BBC’s Russia Editor Steve Rosenberg has been speaking to political scientist and former Kremlin advisor Sergey Karaganov.
