Armed protesters have stormed the Cop30 conference in Brazil as unrest erupted at the climate summit.
The demonstrators clashed with security at the entrance to the venue, which had to be barricaded with tables.
The UN compound was the scene of this year's UN climate summit which saw thousands of delegates from countries around the world attend.
The protesters were an Indigenous group of people who were part of the group of hundreds who marched to the venue in the Amazon city of Belem on Tuesday.
Multiple batons were confiscated by security at the scene.
According to an eyewitness, one guard was rushed from the scene in a wheelchair while clutching his stomach.
Another guard, who had a fresh cut above his eye, said that he had been struck by a heavy drumstick thrown from the crowd.
The protesters have since been dispersed from the area, and delegates have been allowed to leave having earlier been kept inside for their own safety.

Indigenous communities have played a key role at this year's summit, and Brazil's President Inacio Lula da Silva highlighted their importance.
Dozens of leaders arrived by boat earlier this week to participate in the talks, demanding more say in how forests are managed.
The demonstrators waved flags and banners which read: "Our land is not for sale."
One Indigenous leader from the Tupinamba community near the lower reaches of the Tapajos River in Brazil said they were unhappy about the ongoing development in the forest.

Gilmar said: "We can't eat money. We want our lands free from agribusiness, oil exploration, illegal miners and illegal loggers."
The conference, which began on November 10 and will run until November 21, has been met with controversy due to its location on the outskirts of the Amazon rainforest.
In March it was revealed that a new four-lane highway was being built through tens of thousands of acres of protected forest in order to ease traffic into the city of Belem for the conference.
More than 50,000 people, including world leaders and other delegates, were expected to attend the conference.

Prince William and Sir Keir Starmer were among the British delegation at the summit.
The Prince of Wales urged world leaders to take immediate environmental action in a speech written in partnership with his father, King Charles.
Alongside the Prime Minister, Ed Miliband and Sir Sadiq Khan also made the 5,700-mile journey by Ed Miliband and Sir Sadiq Khan at the conference, all of whom have spoken at length about net zero in the UK.
Mr Miliband is set to make the 12,000-mile round trip to Brazil for a second time when he returns this Saturday.
In total, it is estimated his travels will have cost the British taxpayer around £22,000.

He will have also created around six tons of CO2 emissions, equivalent to the average annual carbon footprint for a household in the UK.
Another less senior figure who made the trip was Labour Mayor of West Yorkshire, Tracy Brabin.
She lauded Sir Sadiq's "inspirational leadership" saying: "Mayors are the tugboats of change pushing tankers of government towards a greener world where no one is left behind."
Last year, at the Cop29 in Baku, Azerbaijan, nearly 500 delegates were sent by the British Government at the taxpayer's expense.
GB News revealed this amounted to 1,079,000 air miles, the equivalent of flying to the moon nine times.
