BBC: Russian President Vladimir Putin has ordered his defence minister to impose a 36-hour ceasefire on the Ukrainian frontline, beginning on Friday.
The ceasefire, scheduled to start at 12:00 Moscow time (09:00 GMT), will coincide with the Russian Orthodox Christmas.
Mr Putin asked Ukraine to reciprocate, but Kyiv quickly rejected the request.
Ukraine's foreign minister has said the announcement "cannot and should not be taken seriously".
The Kremlin statement appeared to stress that President Putin ordered his troops to stop fighting not because he was de-escalating - Putin never de-escalates - but because he had listened to an appeal from the head of the Russian Orthodox Church.
Patriarch Kirill had, earlier in the day, called for a Christmas truce to allow believers to attend church services for Orthodox Christmas. » | Will Vernon in Moscow & Samuel Horti in London, BBC News | Thursday, January 5, 2023
