In Dhaka, authorities are still holding five of the 13 hostages rescued when commandos stormed an upscale restaurant in the city's diplomatic zone Saturday morning, killing six of the attackers and capturing one. Investigators are searching for clues about the gruesome attack that left 28 dead, and the country's police chief says authorities will be interrogating two men, including a suspected militant, who were detained during the operation. A second official says the five former hostages still being held include a Canadian citizen of Bangladeshi origin and a Bangladesh-born British citizen. It wasn't clear if all five were suspects, or if they were being held because authorities thought they might offer information in tracing the origins of the attack, the AP reports.
Bangladesh police have said they're investigating whether the attackers had links to ISIS, which claimed responsibility for the attack. The bodies of the seven Japanese citizens killed in the attack on the Holey Artisan Bakery were returned home on Tuesday. Japanese Foreign Minister Fumio Kishida, Bangladesh Ambassador Rabab Fatima, and other officials laid bouquets of flowers in between the boxes holding the bodies after they were lowered from a Japanese government plane at Tokyo's Haneda Airport. Nine Italians were killed in the restaurant, and the Italian Foreign Ministry has posted travel advisories saying it could not exclude the possibility of further attacks in Bangladesh. (The victims also include three US college students.)
