NINE activists from the Black Lives matter campaign were arrested at London City Airport just before dawn on Tuesday after erecting a tripod, chaining themselves together and lying down on the runway. The campaign posted images of protesters lying on the runway after unfurling banners.
All flights had to be cancelled whilst police tried to negotiate with them to leave.
Black Lives Matter UK said the action was taken in order to "highlight the UK's environmental impact on the lives of black people locally and globally".
A statement said: "Whilst at London City Airport a small elite is able to fly, in 2016 alone 3,176 migrants are known to have died or gone missing in the Mediterranean.
"Black people are the first to die, not the first to fly, in this racist climate crisis.
"We note, however, that the UK is willing to charter special flights to remove black people from the country based on their immigration status."
