Rio De Janeiro: The judge overseeing the probe that led to the arrest last week of suspected Islamist militants in Brazil said Facebook Inc. and Twitter Inc. co-operated with investigators by providing information about the suspects' use of both social networks.

In an interview late Sunday with Fantastico, a weekly news program on the Globo television network, Judge Marcos Josegrei da Silva said cooperation by both companies, after a judicial order tied to the investigation, was instrumental to understand the nature of discussions carried out by the suspects, a 12th of whom was detained late Sunday.
