Two alleged militants were killed in a joint operation by police and Rapid Action Battalion (Rab) in Kagmara area of the district town this morning.
The deceased could not be identified immediately.
Acting on a tip-off that a gang of militants is staying at the house, the law enforcers conducted a drive there around 11pm, said Mahbub Alam, superintendent of Tangail police.
Sensing the presence of law enforcers around their house, the militants opened fire at them.
As the law enforcers retaliated, it triggered a gunfight, leaving two militants dead and two others injured.
