Nicolas Maduro, the Leftist leader of Venezuela, blamed far Right opponents, neighbouring Colombia and financiers based in Florida for what he said was an assassination attempt with a drone in Caracas on Saturday night.

He appeared on TV hours after cutting short a speech to the country's military amid scenes of panic to point the finger at a familiar list of enemies.

Officials said two drones loaded with explosives went off during the president's speech. However, firefighters disputed that version of events, saying a gas tank had exploded in an apartment.

In an address to the nation, Mr Maduro said: "That drone was coming for me but there was a shield of love. I am sure I will live for many more years."

He said initial investigations pointed to the far Right and to Colombia.
