Ukraine launched a large-scale drone attack on Russia overnight, forcing multiple airports to close in Moscow. Kyiv struck the Mikron microelectronics plant in Zelenograd, a key producer of microelectronics and semiconductors which are used to develop missile, air defence and radar systems.

German Chancellor Friedrich Merz has pledged to help Ukraine develop its own long-range missile systems that would be free of any Western-imposed limitations on their range and targets.
