Bangladeshi forces stormed an upscale Dhaka restaurant to end a hostage-taking by heavily armed militants early Saturday, killing six of the attackers and rescuing 13 captives including foreigners. The military said 20 hostages were killed during the 10-hour standoff, and a survivor’s father said the attackers spared people who could recite verses from the Quran. The overall toll of 28 dead included two police officers who were killed at the start of the attack. The Islamic State group claimed responsibility for the attack, according to the SITE Intelligence Group, which monitors jihadist activity online. The Amaq news agency, affiliated with IS, also posted photos purportedly showing hostages’ bodies. The authenticity of the images could not be confirmed.
