To mark the first month of Russia's bloody war in Ukraine, Brits are being encouraged to stand in solidarity with Ukrainians with a march in London.
On Saturday 26 March, thousands will gather on Park Lane, West London, and walk through the streets to show their support for the victims of Putin's brutal atrocities.
In a message to followers, London Mayor Sadiq Khan wrote: "In an urgent video message, President Zelensky has called on the world to make a stand — for Ukraine, for freedom, and for peace.
"We must answer that call.
"This Saturday, one month on from President Putin’s criminal invasion, thousands will walk through the streets of London in solidarity with the people of Ukraine. Will you join us?"
He finished: "This is our chance to send a message that echoes around the world: London stands with Ukraine, and this atrocity must end now.
"I hope to see you then."
The London Stands With Ukraine event starts at 2pm on Park Lane and proceed along the streets of the capital 1.4 miles to Trafalgar Square, where a vigil will be held between 3 and 5pm.
A light installation by Yoko Ono named Imagine Peace will be beamed up on the Piccadilly Lights in a powerful message of solidarity.
Anyone who wants to donate to help the victims of conflict will be encouraged to donate to the United Nations’ Central Emergency Response Fund (UNCERF).
It comes after Ukraine's President Zelensky begged the West for more weapons and assistance, and claimed Russia had used damaging white phosphorus weapons to kill children - similar to its tactics in Syria in 2015.
The banned munitions spread a powder that ignites on contact with oxygen and causes severe burns. It is not permitted under the Geneva convention to use white phosphorus in civilian areas.
"To save people and our cities, Ukraine needs military assistance without restrictions. In the same way that Russia is using its full arsenal without restrictions against us," Zelensky told NATO representatives over video-link as he asked for more military support to repel the invaders.
"You can give us one percent of all your planes. One percent of your tanks. One percent!"
He added on Thursday: "This morning, by the way, phosphorus bombs were used. Russian phosphorus bombs. Adults were killed again and children were killed again.
"The Alliance can once more prevent the death of Ukrainians from Russian strikes, from Russian occupation, by giving us all the weapons we need."
