Brazil has upped the ante in security for the Rio de Janeiro Olympic games after the truck massacre in Nice claimed 84 lives.
The stakes got higher after the SITE intelligence internet monitor reported that a group calling itself "Ansar al-Khilafah Brazil" pledged to ISIS. The group follows ISIS leader Abu Bakr al-Baghdadi, and promotes ISIS propoganda in Portuguese, Arabic, and English.
Authorities are now planning more security cordons, further roadblocks, and to frisk visitors at the Olympic games, set to start in 3 weeks.
