Volodymyr Zelensky has called on EU leaders at a crunch summit urgently to agree to a multi-billion euro loan in frozen Russian money to fund Ukraine's military and economic needs, BBC reported. 

Ukraine is months from running out of cash and Zelensky said without an injection by spring Ukraine "will have to reduce production of drones".

Most of Russia's €210bn (£185bn; $245bn) worth of assets in the EU are held by Belgium-based organisation Euroclear. Until now Belgium and some other member states have said they are opposed to using the cash as a "reparations loan".
