Trump has threatened 'very severe' tariffs on Russia if a ceasefire is not agreed by the specified date. The UK has already provided £150 million in air defence missiles and artillery rounds to Ukraine in the past two months,

Russia's Defense Ministry on Sunday claimed to have shot down at least 26 Ukrainian drones over the Moscow region.

Russia launched hundreds of drones and more than two dozen missiles in a massive attack on Ukraine overnight, killing at least two people, including one in the capital, Kyiv, which came under fire a day after President Volodymyr Zelenskyy proposed holding a fresh round of peace talks.

Ukrainian drone attacks on Moscow caused massive traffic disruptions at the Russian capital's four airports, officials said on Sunday. In the Selenograd district, the strikes also damaged numerous high-rise buildings and cars were set on fire,

Russia unleashed one of its largest aerial assaults on Ukraine in recent months, only hours before the U.K. and Germany are to chair a meeting to discuss U.S. President Donald Trump's plans for NATO allies to provide Ukraine with weapons.

Meanwhile the Ukrainian capital of Kyiv came under heavy bombardment overnight into Monday, in what officials described as the worst aerial assault on the capital in months.

President Volodymyr Zelensky said that Ukrainian ambassadors will receive detailed instructions on July 21 on how to proceed with the recovery of the awarded funds.

Moscow mayor Sergei Sobyanin said on Saturday that air defence systems had downed two drones en route to Russia's capital.
