Environmental protesters have occupied a bridge in Edinburgh as part of nationwide demonstrations demanding action to tackle climate change.

Hundreds of activists from the Extinction Rebellion Scotland group blocked North Bridge in the capital as they called for the Scottish Government to declare a climate emergency.

The entire bridge was blocked by the protesters, who were joined by dozens of cyclists that converged on the city centre, causing travel disruption and long tailbacks on either side of the train station.

Organisers said they intended to occupy the bridge until 9pm with their peaceful demonstration.
