While Russian missile and drone attacks have been unrelenting over more than three years of war, they have intensified in recent weeks amid U.S.-led peace talks.

Ukrainian President Volodymyr Zelensky said nations need to apply "real pressure" on Russia to end its attacks on Ukraine following Russian air strikes on a residential area on Friday.

KYIV (Reuters) - Russia launched an overnight air strike on Kyiv, with the city's air defence forces trying to repel the attack, the military administration and the mayor of the Ukrainian capital said on Sunday.

The Trump administration says it will soon be clear if Russia's Vladimir Putin really wants a peace deal in Ukraine, as France and Britain accuse him of playing for time.

The Trump administration quietly lifted travel sanctions on Kirill Dmitriev, one of Vladimir Putin’s closest advisers, so he could come to Washington for talks.

The Kremlin said on Friday that Russian President Vladimir Putin and U.S. President Donald Trump had no plans to talk after a visit to Washington by Putin's investment envoy as wider negotiations over a ceasefire in Ukraine appeared stalled.
