A court in Italy has convicted over 230 defendants in one of the country's largest-ever mafia trials, targeting the 'Ndrangheta crime group in Calabria. The trial lasted nearly three years, with more than 330 suspected mobsters and their alleged associates facing charges including extortion and drug trafficking. The verdict, which took judges over an hour to read, resulted in heavy penalties for two local mafia leaders. Monday's first-instance ruling can be appealed by both the defence and the prosecution.
