Brazil arrests group plotting ‘acts of terrorism’ before Olympics:

From Reuters and the BBC

Brazil’s federal police on Thursday arrested 10 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. The arrests were made in the southern state of Parana.

News site Globonews reported that the members of the group were linked to Islamic State (IS). It was not possible to immediately confirm this.

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.

The authorities said they were not members of so-called Islamic State but had tried to make contact with the group.

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.
