President Joe Biden's apparent green light for Ukraine to strike Russia with US-made long-range missiles has caused consternation among Donald Trump's allies. Trump himself has not commented, but he won the election after promising to end the war - and people close to him have condemned the move as dangerous escalation.

Ukrainian Ambassador Vasyl Myroshnychenko says Russia has demonstrated they are prepared for a protracted war against Ukraine.

Russia slammed the US for its latest decision to send antipersonnel mines to Ukraine to aid its defences against invading Russian forces.

Russia has warned that it will retaliate with full-scale nuclear war after Ukraine fired long-range US missiles at its territory for the first time.
