Anti-Donald Trump activists have shut down Forth Road Bridge ahead of the US President's visit to Scotland tonight.
The bridge, located just outside Edinburgh in South Queensferry, was closed shortly after protesters were seen abseiling down at around 1.05pm.
Photos from the scene showed around a dozen activists abseiling down from the bridge.
Climate campaign group Greenpeace confirmed its activists abseiled down the 156 metre bridge to block an Ineos tanker.
Activists were also seen clutching six red banners which carried the slogan: "Plastics Treaty Now."
Police Scotland urged the public to stay away from the area as officers continue to deal with the incident.
The force said: "The Forth Road Bridge is closed due to a protest reported to police around 1.05pm on Friday, 25 July.
"Officers are in attendance and engaging with those involved. Please avoid the area."

Traffic Scotland added: "Users of the Forth Road Bridge are advised to use the Queensferry Crossing at this time due to a police incident."
Greenpeace confirmed its protest was intended to block an Ineos tanker from delivering fracked gas cargo bound for the Sir Jim Ratcliffe-owned Grangemouth petrochemical facility.
Amy Cameron, programme director at Greenpeace UK, said: "Ratcliffe tries to distract us with sports teams and sponsorships, but we’re not going to let him fill our planet with plastic, so he can fill his pockets with profit."
Greenpeace activists have been supported by a rescue crew on the bridge and a boat team in the river.

The giant Independence tanker, which was targeted during the protest, has sailed across the Atlantic carrying 27,500 cubic metres of ethane.
Despite Forth Road Bridge predominantly being reserved for buses and taxis, pedestrians and cyclists are also permitted to use the structure.
The protest comes amid fears of further demonstrations during Trump's visit to his mother's homeland.
Scottish First Minister John Swinney, who will meet Trump, called the visit a "platform to make its voice heard on the issues that matter, including war and peace, justice and democracy".

Demonstrations are expected to gather at Trump Turnberry in South Ayrshire, where the 47th President looks set to spend the weekend.
A 10-foot high perimeter fence has been erected around the resort to keep out protesters.
Further demonstrations are expected across major Scottish cities, including Glasgow, Edinburgh and Aberdeen.
Scottish Green MSPs Ross Greer and Patrick Harvie have confirmed that they are planning to join the demonstration outside the US Consulate on Regent Terrace on Saturday.

Trump is expected to touch down at Glasgow Prestwick Airport on Air Force 1 between 7.20pm and 8.05pm tonight.
A no-fly zone will be in place from 7.30pm to 8.50pm between the airport and his Trump Turnberry.
During his four-day visit to Scotland, Trump is expected to meet with Sir Keir Starmer.
Despite Trump suggesting the pair could meet tonight, No10 insists that the Prime Minister will meet the US President on Monday.
