The European Union's future is in jeopardy if it cannot come up with a joint financial response to combat the new coronavirus, Spanish officials warned on Wednesday, after the bloc failed to agree on more support for their reeling economies.

Government spokeswoman Maria Jesus Montero said Europeans will begin to lose trust in the EU if it does not act together in the crisis, which she compared to the Second World War.

"We need the help of other countries, and that's why the European Community was originally formed, at that time after a physical war, now we are fighting a war against an epidemic," she said in an interview on Antena 3 TV channel.
