Several people were injured as a major clash broke out between DYFI and Youth Congress activists in Kannur following a flex board row. The incident was reported on Thursday night during a protest over the alleged vandalism of a political poster. The development comes after the Youth Congress planned a satyagraha in Payyanur following allegations by former area secretary and district committee member P Unnikrishnan of irregularities in the martyrs’ fund. Then, the tension escalated when DYFI and SFI workers allegedly tore down posters related to the protest.
