"SELFISH" protesters sparked traffic chaos during this morning's rush hour by suspending themselves from London's Tower Bridge.
Two members of the eco-mob were seen dangling from the landmark - closing it in both directions and bringing the capital to a standstill.
They also draped a huge 22 metre banner reading "end fossil fuels now" over the side of the iconic structure and let off red flares.
Police then closed the route, causing severe delays - on top of those created by the closure of Westminster Bridge for maintenance.
One man, on his way to work at a hospital, blasted the environmental activists for halting his journey.
He said on Twitter: "These lot think it's ok to block Tower Bridge from all traffic. Selfish."

Ben Hersh, 24, an office worker who regularly uses the bridge to get to work, also said the protestors should "grow up" and "stop taking aim at regular people".
"I know that climate issues are important, but why are we always targeted?" he said
And an Uber driver said that he was "worried" he wouldn't make any money today as a result of the disruption.
Muhamed Q, 44, said: "My main money source is this and I use this bridge most of the time."

The green gang, which struck at around 7.30am, are from eco groups Just Stop Oil and Extinction Rebellion.
Both have blockaded oil terminals and let the air of out the tyres of fuel tankers over the past week in an attempt to save the planet.
Just Stop Oil yesterday said more than 400 of its activists had been arrested in the last eight days.
The Met Police have not yet arrested anyone in connection with today's incident.
A spokesperson for the force said: "Police were called at 7.30am on Friday, April 8, to protesters on Tower Bridge.
"There has been no arrest at this stage."
The City of London Police confirmed the bridge had reopened just after midday.
London Mayor Sadiq Khan later described the demonstration as "counterproductive".
Speaking at the launch of Labour's local election campaign in Barnet, north London, he said: "I think all campaigns or protests should be peaceful, lawful and safe, and I'm concerned that some of the tactics being used are counterproductive."
