Extinction Rebellion keep control of major London sites into a third day

TfL turns off wifi on tube in bid to thwart group's plans to disrupt public transport network

Climate activists have kept control of four sites in London for a second night, with police saying they have caused "serious disruption" affecting half a million people in the city.

After the Extinction Rebellion activist group threatened to disrupt the city's public transport network on Wednesday, Transport for London disabled wifi on the underground at the request of the British Transport Police.
