Islamist militants

Emerging from the appalling, bloody debris are stories of immense courage. There are also unanswered questions about what happened to some of those who died.

It was about 20:45 on a Friday evening just before the Islamic festival of Eid. The restaurant - the Holey Artisan Bakery and O'Kitchen in Gulshan, Dhaka's leafiest, most exclusive area - was filling up, mostly with Japanese and Italian customers.

Suddenly, the five young militants burst in shooting and began hacking at the diners with sharp weapons.

Police official Mustafizur Rahman identified the victim as 40-year-old Niloy Chowdhury and said he was hacked to death in his apartment. The motive was not immediately clear.

The victim's family said his real name was Niloy Chottopadhay and that he used a different name on social media.

Asha Moni, the victim's wife, said at least four young people attacked her husband.
