The barrage of exploding drones and missiles appeared to be the most intense attack since President Trump announced a plan to get more weapons for Kyiv.

A Russian factory, described by its director as the world's biggest maker of strike drones, has been shown on the Russian army's TV channel with teenagers helping make kamikaze drones to attack Ukraine.

Russian aviation faced big delays due to the threat posed by Ukrainian drones, while Moscow's attacks on Ukraine killed at least one person.
