Officials hunt for hostage crisis clues

Govt insists extremist Islamic State group has no presence in the nation

Security officials searched on Sunday for evidence and the possible masterminds of the weekend hostage-taking in an upscale restaurant in Bangladesh's capital. The government has denied the Islamic State group's claim of responsibility for the attack that left 28 dead, including six attackers and 20 of the hostages.

Police released photographs of the bodies of five attackers, along with their first names: Akash, Badhon, Bikash, Don and Ripon. The men belonged to the banned domestic group Jumatul Mujahedeen Bangladesh, or JMB, and their families hadn't heard from them in months, according to police. Asked whether they might also have had links with the Islamic State group, Police Inspector General A.K.M. Shahidul Hoque said authorities were investigating that possibility.
