Brazil arrests group plotting 'acts of terrorism' before Olympics -source
By Lisandra Paraguassu
BRASILIA (Reuters) - Brazil's federal police on Thursday arrested members of a group that was preparing "acts of terrorism," a justice ministry source told Reuters, just over two weeks before the Olympics start in Rio de Janeiro.
News site Globonews reported that the members of the group were linked to Islamic State (IS). It was not possible to immediately confirm this.
It was unclear where the operation was taking place or what the specifics of the operation were. Justice Minister Alexandre de Moraes was due to hold a news conference on the operation.
Brazil's intelligence agency said on Tuesday it was investigating all threats to the Rio Olympics, which start on Aug. 5, after a presumed Brazilian Islamist group pledged allegiance to IS.
The SITE Intelligence Group that monitors the internet reported the previously unknown 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.
Brazilian authorities stepped up security measures following the truck massacre in Nice, France last week, planning security cordons, additional roadblocks and the frisking of visitors in Rio de Janeiro for the Olympics.
