Officials from Ukraine and the US are expected to sit down in Riyadh and talk about a possible partial ceasefire on Sunday. The meeting will be taking place sooner than expected and will precede another between delegations from the US and Russian on Monday. On Saturday, the American president said that efforts to stop an escalation in the war were "somewhat under control". For his part, Kremlin spokesman, Dmitry Peskov, said that: "We are only at the beginning of this path".
