Overnight Russian attacks on Ukraine have killed one person in the southern port city of Odesa, according to officials. Meanwhile, state media in North Korea says Kim Jong Un has recently sanctioned the "mass production" of suicide drones.

Russia and Ukraine have exchanged record numbers of drone strikes, with Moscow launching a total of 145 drones on Saturday night – the most ever in a single night-time attack of the war.

Russia overnight launched a “record” 145 drones at Ukrainian territory, according to Ukraine’s air force, 62 of which were shot down. A further 67 were “lost,” the air force said, a likely reference to electronic jamming that caused the drones to veer off course.
