The mayor of Ukraine’s capital Kyiv, Vitali Klitschko, has asked European politicians to cut off all commercial ties with Moscow, saying payments to Russia are covered in “blood” and help to fund its army.

“Every euro, every cent you receive from or send to Russia has blood; it is bloody money and the blood of this money is Ukrainian blood. The blood of Ukrainian people.”

Klitschko also described the “genocide of Ukrainians” following a visit to Kyiv’s satellite towns like Bucha this week.

He says he saw dead civilians, including an old woman, and a car with a white flag and the letters “children” on the outside that had been shot at and had blood inside.

Klitschko was speaking via video link to a mayors’ conference in Geneva.
