Heathrow tunnel blocked in climate change protest

A protest by anti-airport expansion group Plane Stupid at Heathrow Airport has caused delays to traffic trying to reach terminals two and three.

The airport said the disruption was centred on the "inbound tunnel" and urged "passengers to allow extra time getting to the airport today".

The Metropolitan Police are on site and are trying to ease the traffic congestion as BBC London's Gareth Furby explains what he can see at the scene.
