LONDON (AP) — Climate change protesters have glued themselves to a train and blocked major London intersections on the third day of a civil disobedience campaign.

Three demonstrators were arrested after stopping Docklands Light Railway services at Canary Wharf station on Wednesday.

Police have arrested more than 300 people since Monday during protests by the group Extinction Rebellion.

Demonstrators continue to block sites including Waterloo Bridge over the River Thames and the Oxford Circus and Marble Arch intersections. Many bus routes have been disrupted, to the frustration of commuters.

Lawyer Farhana Yamin, one of those arrested, apologized to public transit users. But she told BBC radio that "we need to take actions that are disruptive so everyone understands the dangers we're facing right now."
