Brazil has arrested 10 people on suspicion of belonging to a group backing Islamic State (IS) and preparing acts of terrorism during next month's Olympics in Rio de Janeiro, Justice Minister Alexandre Moraes said.

The justice ministry said in a statement that the operation spanned nine states in Brazil.

A court in the southern state of Parana said there were indications that the group was planning to use weapons and guerilla tactics to achieve its aim.
