MIAMI: US President Donald Trump on Monday urged Venezuela's military to accept opposition leader Juan Guaido's amnesty offer, or stand to 'lose everything,' as a crisis deepened over President Nicolas Maduro's refusal to let in desperately needed humanitarian aid.

Bringing in humanitarian aid is crucial to the viability of Guaido, who has denounced Maduro's re-election last year as fraudulent and in January declared himself interim president, a move recognized by some 50 countries.
