Video: Heathrow Climate Change Protesters Facing Prison After Guilty Verdict

The group of 13 climate change protesters who blocked the runway of Heathrow Airport have been found guilty of aggravated trespass and entering a security restricted area.

The judge said the defendants were all "principled people" and Heathrow is in breach of EU emission regulations, but she did not accept that their actions were necessary to prevent death or serious injury.
