Environmental protesters are planning to shut down Heathrow Airport in London for 10 days this summer.
They says the plans will go ahead if the UK Government doesn't cancel plans for a third runway.
Extinction Rebellion says it's not about disrupting the public.
In a statement they said: 'On June 18, we plan to carry out nonviolent direct action to ensure Heathrow Authorities close the airport for the day, to create a ‘pause’ in recognition of the genocidal impact of high carbon activities. Such as flying, upon the natural world
'This is not about targeting the public, but holding the Government to their duty to take leadership on the climate and ecological emergency.'
It's considering the action from the 1st of July, as well as a one-day protest on the 18th of June.
