He adds that Maduro has been flown out of the country, though details remain scarce.

Venezuela announces a state of national emergency and rejects and denounces “military aggression” – it has not yet responded to Trump’s post.

“My heart was pumping and legs were shaking,” an eyewitness in Caracas tells the BBC after explosions were heard across the city.

Footage shows huge plumes of smoke as fires rage.

It follows weeks of heightened tension as Trump ramped up pressure on Maduro.

Venezuela’s Defence Minister has announced an immediate deployment of military forces across the country.

Speaking in Spanish in a video address, Vladimir Padrino López called for a united front of resistance in the face of “the worst aggression” ever against Venezuela, adding that Venezuela was following “Maduro’s orders” that all armed forces will be deployed.

“They’ve attacked us but they will not subdue us,” says the defence minister.

Venezuela’s Vice President demands proof of life, as Maduro’s whereabouts unknown: We’ve just heard from Venezuela’s Vice President Delcy Rodríguez.

She says the government does not know the whereabouts of President Maduro or the First Lady Cilia Flores.

She added that the government demanded “immediate proof of life” for them both.

Details of Maduro’s capture remain thin; The US has long accused Nicolás Maduro of leading an international drug trafficking organisation, something that Maduro denies.

Trump did not give more detail about how Maduro was captured or where he has been taken. The Venezuelan government have not yet confirmed this. The US had offered a $50m reward for information leading to the arrest of Maduro.

That, along with the huge military build-up in the region over the last few months, were interpreted in the region as encouragement for someone inside the country to turn against him.

Donald Trump adds on Truth Social that there will be a news conference at 11:00 EST (16:00 BST), at the president’s Florida residence Mar-a-Lago.
