BRASILIA (Reuters) - Brazil's intelligence agency said on Tuesday it was investigating all threats to next month's Rio Olympics after a presumed Brazilian Islamist group pledged allegiance to Islamic State (IS) less than three weeks before the Games.
The SITE Intelligence Group that monitors the internet reported that a group calling itself "Ansar al-Khilafah Brazil" said on the Telegram messaging app on Sunday that it followed IS leader Abu Bakr al-Baghdadi and had promoted IS propaganda in Arabic, English and Portuguese.
