Roger Hallam, who co-founded the climate movement Extinction Rebellion, whose activists often use civil disobedience as a protest method, is sentenced to five years in prison by a British court.
The prison sentence is believed to be the longest handed down for non-violent protests in the UK, writes The Telegraph.
He is convicted for planning, as part of the "Just stop oil" campaign, which criticizes the oil industry, a blockade of traffic on the M25 motorway for four days in November 2022.
An additional four activists were sentenced to four-year sentences for the same offense.
Corrected: In an earlier version of the text, an incorrect description of the sentence was provided.
