Helicopter attacks Venezuelan court

Venezuela's Supreme Court has been attacked by grenades dropped from a helicopter in what President Nicolás Maduro called a "terrorist attack".

Footage on social media shows a police helicopter circling over the city before shots and a loud bang are heard.

The police officer said to have piloted the stolen aircraft issued a statement denouncing the "criminal government". His whereabouts are unknown.

It comes after mass protests against the political and economic crisis.

The Supreme Court is regularly criticised by the Venezuelan opposition for its rulings which bolster Mr Maduro's hold on power.

What happened?

In an address from the presidential palace, President Maduro said the helicopter had flown over the Supreme Court and also the justice and interior ministries.

Officials quoted by Reuters news agency said four grenades were dropped on the court and 15 shots had been fired at the interior ministry.

No injuries were reported but Mr Maduro said "a social event" had been taking place at the Supreme Court and the attack could have caused "dozens of deaths". One of the grenades failed to detonate, he added.

forces to defend the peace," he said. "Sooner or later, we are going to capture that helicopter and those who carried out this terror attack."

Who flew the helicopter?

The police officer identified himself as Oscar Pérez in video statements posted on the social media platform Instagram.

Appearing in military fatigues and flanked by armed, masked men in uniform, he appealed to Venezuelans to oppose "tyranny".

"We are a coalition of military employees, policemen and civilians who are looking for balance and are against this criminal government," he said.

"We don't belong to any political tendency or party. We are nationalists, patriots and institutionalists."

He said the "fight" was not against the security forces but "against the impunity of this government. It is against tyranny".

It is not clear how much support, if any, the officer has.

Mr Maduro said the pilot had worked for former Interior and Justice Minister Miguel Rodriguez Torres, but was no longer with him.

Why now?

There have been almost daily anti-government protests in Venezuela for over two months as the country's economic and political crisis worsens.

Those opposed to the government say they are determined to keep protests going until fresh elections are called and the government is ousted.

More than 70 people have been killed in protest-related violence since 1 April, according to the chief prosecutor's office.

Could this have been a coup attempt?

Although President Maduro called the incident an attack by "terrorists" seeking a coup it is not clear how much support, if any, the police officer has.

Earlier on Tuesday, Mr Maduro reiterated his allegations that the US was supporting coup attempts against his government and warned President Donald Trump that Venezuela would resist such a move.

On Monday, he announced that five people had been arrested, accused of plotting against him and preparing for a US invasion.

However, Venezuela certainly has a history of coup attempts:

In 1992, the late Hugo Chávez tried to overthrow the government of President Carlos Andres Pérez. The attempt failed and Chávez was arrested and imprisoned. He would eventually be elected president in 1998

In 2002, Chávez himself survived an attempted coup by rebel military officers
Months later, security officials foiled another attempt by leading political and military opposition figures
