"Ukraine is not a testing ground for weapons," says president Volodymyr Zelenskyy as he warns Russia wants to "spread fear and panic".

Russia has removed a senior general in Ukraine for giving misleading reports about the progress of the war as Defence Minister Andrei Belousov tries to clear out poor commanders, pro-Russian war bloggers and Russian media said.

Russian forces launched drones across Ukraine overnight on November 24 for another air attack. The enemy kamikaze drones entered Ukraine’s airspace from the northern direction, according to the Air Force of the Armed Forces of Ukraine and the air alert map.

Kyiv has been hit by what Ukraine's air force described as the largest Russian drone attack of the war so far.
