BRUSSELS: Belgian authorities have detained five people, including two brothers, after two days of raids related to Paris attacks. The federal prosecutor's office said two people were detained following a house search Monday in the Laeken district of Brussels. On Sunday evening, another Brussels house was searched on orders from an investigating judge specializing in terrorism. Two brothers found there were taken in for questioning, as well as a friend. The prosecutor's office said an analysis of phone records led to Sunday's search. Authorities said they found no weapons or explosives at either residence, and did not identify those detained. The investigating judge will decide later on whether to keep the five in custody. The Islamic State group claimed responsibility for the November 13 Paris attacks, which left 130 people dead.
