At least 20 people were injured in rough-and-tumble fighting between two factions of the Bangladesh Chhatra League (BCL) Barguna unit during a National Mourning Day discussion Monday. It happened around 11am at Barguna Shilpakala Academy premises when district BCL President Rezaul Kabir Reza, General Secretary Taushikur Rahman Imran, Senior Vice-President Sabuj Mollah and Central BCL Member Rishat Hassan Prince and their followers came to attend the programme.  The groups got into a scuffle following a heated argument during the discussion.

"Later police had to use batons to bring the situation under control." "Two BCL activists were held from the spot, and several of them suffered injuries. Also, four sharp weapons were recovered from a room of Barguna Launch Terminal," Tariqul added. Since July 24, after the new committee of the Barguna BCL was announced, there have been sporadic clashes between BCL activists and leaders who were included in and excluded from it.
