At least one person was killed and more than 21 were injured in post-upazila polls violence in Brahmanbaria and Barguna districts Monday night.

A youth was killed and at least five others were injured during a clash between the supporters of a newly elected chairman and his defeated rival at Kurighat village under Nabinagar upazila in Brahmanbaria.

Saidul Islam, 36, a supporter of Awami League rebel and independent candidate Moniruzzaman Monir, who won the upazila election at Nabinagar, was stabbed to death, reports our correspondent in Brahmanbaria.

Saidul, who hailed from Nandura village of Natghar union, was severely stabbed when he took part in a victory rally at Kurighat village around 8:00pm, locals said.
