Flights have been disrupted at London City Airport after a group of Black Lives Matter protesters occupied a runway this morning.
Seven of the protesters have been arrested, but two are still on the runway and flights remain disrupted.
Police were called to the airport at 5.40am to reports protesters were demonstrating on the runway.
The protesters reportedly bypassed security by using a rubber dinghy to cross the docks.
Police say they erected a tripod and locked themselves together on the runway.
Met Police officers began to arrest the protesters around 9.30am after specialist officers arrived to "unlock" the activists.
Flights from the airport have been delayed and all flights due to land have been diverted to Gatwick and Southend airports.
Police said the seven have been held on suspicion of aggravated trespass, being unlawfully air-side and breaching airport by-laws.
In a statement, Black Lives Matter UK said: "This action was taken in order to highlight the UK's environmental impact on the lives of black people locally and globally.
"As the largest per capita contributor to global temperature change and yet among the least vulnerable to its deadly effects, the UK leads in ensuring that our climate crisis is a racist crisis."
The group added that the planned expansion of London City Airport "consigns the local community in Newham to further deterioration of their environment".
The group says the airport caters to people working in financial services - making it a facility to help the wealthy.
Black Lives Matter said "when black people in Britain are 28 percent more likely to be exposed to air pollution than their white counterparts, we know that environmental inequality is a racist crisis."
A witness told the Evening Standard: "They got onto the runway using a rubber dinghy from the dock.
"They are on the runway surrounded by police. I'm not sure if they are chained together but they are huddled together."
Last month, Black Lives Matter staged protests in London, Birmingham, Nottingham and Manchester as part of a "nationwide shutdown" calling for greater awareness of discrimination against black and minority ethnic communities following a spate of shootings in the US.
Ten Black Lives Matter UK activists were arrested after demonstrating near Heathrow.
