Russia-Ukraine war: What happened today (June 6)

A mural on a wall in Kyiv on Monday depicts an image of "Saint Javelina" — the Virgin Mary cradling a U.S.-made Javelin. These missiles are among the weapons sent by Western allies to Ukrainian forces to aid in their fight against Russia. The Javelin is widely considered a symbol of Ukraine's defense.

As Monday draws to a close in Kyiv and in Moscow, here are the key developments of the day:

The United Kingdom is sending long-range missiles to Ukraine, defying Russia's warning it will bomb such weapons supplied by the West. British Defense Secretary Ben Wallace said the U.K. will deliver multiple-launch rocket systems that can strike targets up to 50 miles away with great precision, boosting Ukrainian forces' capabilities against Russia. This follows President Biden's announcement last week that the United States was sending Ukraine more advanced rockets than previous shipments.
