Ukraine fights on in ruined Avdiivka despite severe weapons shortage

Nato Secretary-General Jens Stoltenberg has warned that the US failure to approve continued military assistance to Ukraine is already having an impact on the battlefield, although he expects Congress will eventually approve an aid package. Republicans in the lower House of Representatives are holding up a $95bn (£75bn) foreign aid package for Kyiv.

Meanwhile, Russia has continued attacks on Ukrainian cities. After months of heavy fighting, Russian forces appear close to surrounding the ruins of Avdiivka, where frostbite is taking its toll on Ukrainian troops.
