Bangladeshi police say they have stormed a hideout near Dhaka and killed the suspected planner of a cafe attack last month that left 22 people dead.
"Tamim Chowdhury is dead," said senior police officer Sanwar Hossain, referring to the Bangladeshi-Canadian suspected mastermind.
Two other suspected militants were killed by police during the raid.
The cafe attack began on 1 July when the militants entered the Holey Artisan Bakery in Dhaka.
They held hostages for 12 hours before police stormed the cafe, rescuing 13, killing six gunmen and arresting another.
Twenty hostages and two police officers were killed in the attack, the worst in the country's history.
"Tamim Chowdhury is dead. He is the Gulshan attack mastermind and the leader of JMB (Jamayetul Mujahideen Bangladesh)," Mr Hossain said. The JMB is a banned Islamist militant group.
Police earlier engaged in an hour-long gun battle with extremists at Paikpara in Narayanganj, 25km (16 miles) south of Dhaka, he added.
Chowdhury returned to Bangladesh from Canada in 2013.
