A 91-year-old man was among 10 people who have been arrested while taking part in a protest with climate activists Extinction Rebellion. The pensioner is in a group of five, which also included an 83-year-old woman, who had broken away from a demonstration near the port of Dover that had been sanctioned by authorities in Kent.
