Turning to the US now, where President Biden has been outlining how the US intends to help Ukraine, as the war drags on.
The White House has confirmed it will commit $1bn (£764m) to the direct transfer of weapons to Ukrainian forces.
Biden says the continued support is about "making sure Ukraine will never be a victory for Putin".
He notes US security assistance to Ukraine over the past year - $650m in weapons and $350m in additional aid - amounts to "more than we had ever provided before".
The newly-announced support includes drones, 800 anti-aircraft systems and 9,000 anti-armour systems, as well as machine guns, shotguns, grenade launchers and 20 million rounds of ammunition.
Allies too have stepped up their support to unprecedented levels, Biden adds.
"We're going to stay the course and do everything we can to push for an end to this tragic, unnecessary war," he says.
