Venezuela latest: 'Rambo' rebel helicopter pilot Oscar Perez cornered by government security forces

Venezuela's "Rambo" rebel helicopter pilot has been cornered by government forces as five of his band were arrested, with reports suggesting he may have been killed in the shoot-out.

Oscar Perez made international headlines last year when he stole a police helicopter and used it to attack government buildings.

On Monday, authorities detained members of a "terrorist cell" linked to him and killed several other militants during a shoot-out in a poor area outside Caracas.

An unnamed member of the Venezuelan government was quoted by CNN as saying Mr Perez had been killed during the incident.

Mr Perez appeared with a bloody face in nearly a dozen dramatic Instagram videos earlier on Monday, saying he was surrounded by authorities shooting at him with grenade launchers.

State television later read out an official statement that said two police officers were gunned down in the clashes but did not specify Mr Perez' fate.

A former police pilot, Mr Perez is wanted for using a stolen helicopter to lob grenades and shoot at government buildings in June as well as for breaking into a National Guard unit in December to steal weapons.

President Nicolas Maduro's leftist government has described him as a "fanatic, extremist terrorist" and a manhunt has been under way for months.

Some Maduro critics have questioned whether Mr Perez' attacks were staged in cahoots with the government to justify a further crackdown on the opposition.

Authorities finally tracked Mr Perez down in the poor hillside neighbourhood of El Junquito.

"We're wounded ... they're killing us!" said Mr Perez in one video, seemingly wearing a bulletproof vest as he crouched in what appeared to be a small house. Gunshots were heard in the background.

"Venezuela, don't lose hope ... Now only you have power so that we can all be free," he said in an earlier video, staring into the camera and telling his children he loved them and hoped to see them again.

His last video was posted about 10.30 am (2.30am GMT). A Reuters witness in the area later saw an ambulance speed by and said gunshots were no longer heard.

The Information Ministry did not immediately respond to a request for comment.

Members of Mr Maduro's government scoffed at Mr Perez on Monday.

"What a coward now that he's caught like a rat!" tweeted Prisons Minister Iris Varela. "Where is the courage he had to attack military units, kill and injure officials and steal weapons?"

Mr Perez, who also has been an action film star and portrays himself as a James Bond or Rambo-like figure on social media, has added surreal twists to Venezuela's long-running political drama.

He rose to fame in June after allegedly hijacking a police helicopter, flying over Caracas' centre and firing shots at and lobbing grenades on the Interior Ministry and the Supreme Court.

Mr Perez claimed responsibility for the attack, saying it was to fight what he said was a tyrannical government.

He went into hiding afterwards, only to pop up two weeks later at an opposition vigil for anti-government protesters killed during demonstrations that rocked the country last year.

In December, a video posted on Mr Perez's YouTube account shows armed, masked men taking control of military barracks under cover of night.

They smashed photos of Mr Maduro and his predecessor, the late Hugo Chavez, handcuffed about a dozen soldiers and berated them for supporting a "dictatorship" in Venezuela. Mr Perez says his team stole about 26 AK-103s and more than 3,000 munitions for the rifles, as well as pistols.

Opposition politicians called for due process.

"There is no death penalty in Venezuela," tweeted opposition lawmaker Yajaira Forero. "We demand that Mr Oscar Perez' right to life be respected. If he committed a crime he must be judged by a court, as the law establishes."
