The US has carried out strikes on Venezuela's capital city Caracas.
The city was rocked by explosions early on Saturday morning - before it emerged that Donald Trump had ordered them.
Local reports suggest blasts have been heard at an airbase and a communications centre, both of which are heavily-guarded military or Government-run facilities.
The first blast was recorded at approximately 1.50am local time (5.50am GMT).
Aeroplanes, loud noises and at least one column of smoke were then heard and seen in the early hours of Saturday morning.
The southern area of the city, near a major military base, was left without electricity.
In social media footage, numerous helicopters can be seen flying over Caracas, though it remains unclear whether these are American.
Explosions were also seen at Higuerote Airport, around 50 miles east of Caracas.
CBS News was the first to report that the President had ordered the military action.

For months, Donald Trump had promised land operations in Venezuela in a bid to disrupt the flow of illegal drugs to the States - as well as push dictator Nicolas Maduro to leave.
Mr Maduro, following the strikes, declared a state of national emergency and rejected US "military aggression".
The Venezuelan President then declared the US "will not succeed" in taking his country's resources, which he claimed was the country's goal.
His Government went on to call on all its "social and political forces" to activate their mobilisation plans.
The US Federal Aviation Administration earlier issued a new "Notam", or notice to airmen, barring American aircraft from Venezuelan airspace.
The FAA says there are "safety-of-flight risks associated with ongoing military activity".
Flight tracking service FlightRadar24 currently says there are no aircraft over the country.

Last week, Mr Trump said the US had hit an area in Venezuela where boats are loaded with drugs, marking the first known time Washington has carried out land operations on Mr Maduro's soil.
It was widely reported that the CIA was behind those strikes.
On Christmas Eve, Vladimir Putin evacuated the families of diplomatic staff from Venezuela amid mounting fears of US military intervention.
That came as Mr Trump ramped up sanctions and massively increased his country's military presence in the region.
The US has also completed over 20 strikes on drug boats in both the Caribbean Sea and Pacific Ocean - and has seized sanctioned Venezuelan oil tankers.
