Climate activists from Extinction Rebellion have drawn up plans to use drones to shut London¡¯s Heathrow Airport this summer in a campaign to stop the construction of a third runway at Europe¡¯s busiest airport, the group said.

The internal proposal, seen by Reuters, emerged against a backdrop of renewed campaigning by environmental groups who argue that expanding Heathrow would be incompatible with Britain¡¯s targets to curb greenhouse gas emissions.

¡°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,¡± Extinction Rebellion said in a statement late on Thursday.
