Bangladeshi police hunted on Tuesday for six members of a domestic Islamist group they suspect helped gunmen attack a Dhaka cafe, as officials began questioning families of the militants for clues as to what turned them into killers.
Gunmen stormed the restaurant in Dhaka's diplomatic zone late Friday and killed 20 people, most of them foreigners from Italy, Japan, India and the United States, in an assault claimed by the Islamic State group.
It was one of the deadliest militant attacks in Bangladesh, where the Islamic State and al-Qaida have claimed a series of killings of liberals and members of religious minorities in the past year. The government has dismissed those claims, as it did the Islamic State claim of responsibility for Friday's attack.
