Inspector General of Police (IGP) Shahidul Hoque visited the prayer ground in Kishoreganj on Saturday that hosts the largest congregation of Eid prayers in Bangladesh.
Tens of thousands had gathered to pray on Eid day, when explosions hit a nearby check-post, killing two policemen.
A Hindu woman died during the shootout that followed the blasts. One of the attackers died in the gunfight.
The Eid day attack came less than a week after gunmen stormed the Holey Artisan Bakery and O’Kitchen to kill 20 hostages during an overnight siege before being shot dead by commandos the next day.
The Islamic State claimed responsibility within hours of the attack, reported SITE intelligence, but IGP Hoque rubbished the assertion.
He blamed the JMB, banned more than a decade ago, for the Sholakia attack. No group has taken responsibility for it.
