Hundreds of Extinction Rebellion activists gathered on Waterloo, Blackfriars, Lambeth and Westminster bridges calling for an end to new fossil fuel investments.

Queues of traffic have been forming as a result of the demonstrations.

The Metropolitan Police said it was aware of "pockets of protest" and officers were attempting to control the disruption.

Demonstrators were playing bongos and waving banners, which read: "End fossil fuels now" and "Love in action".

Earlier this week protestors also blocked entrances to major insurance marketplace Lloyd's of London.
