At least 20 people were injured in a clash between two factions of BNP at village Datia in Bera upazila on Friday.

Locals said there had been rivalry between local BNP leaders Goni Fakir and Idris Ali since long over establishing supremacy in the

area. The fierce clash erupted between their supporters over a trifling matter.

Both the groups used batons and lethal weapons in the hourlong clash creating panic in the area. Six of the injured were rushed to the upazila health complex in critical condition.
