Belgium has issued an international warrant for the arrest of a man suspected of having taken part in the Paris attacks with two of his brothers. In France, police have questioned the family of another suspected killer.
Belgian authorities on Sunday issued a warrant for a Belgian-born man believed to have taken part in the attacks across Paris on Friday.
The 26-year-old, named as Abdeslam Salah, was one of three brothers believed involved in the killings, reportedly rented a black Volkswagen Polo used by a group of hostage-takers who killed at least 89 people dead inside the Bataclan concert hall.
One of the three siblings died during the attack, while another was said to have been detained by police.
Belgian prosecutors had earlier said seven people after raids in Brussels on Sunday. Two assailants living in Belgium were among the killers who died during the attacks.
Police have also questioned the relatives of one alleged attacker on Sunday, in an effort to gain clues about the attack.
Strained family ties
At least six people were arrested by French police, including the father and brother of Omar Ismail Mostefai, as well as the brother's wife. The six were detained under a French procedure to gather witness statements, although they were not being held as formal suspects. The AFP news agency reported that Mostefai was not close to his family.
Mourners flee square
The venue, where rock band Eagles of Death Metal were playing a concert, was the scene of the worst carnage on Friday, with at least 89 people killed in apparently coordinated shootings and suicide bombings.
The Paris attacks left at least 129 dead and over 300 wounded, dozens of them critically.
Thousands of mourners fled from the Place de La Republique, which has become a memorial area for those who died in the Friday killings, on Sunday. The alert was apparently sparked by the sound of firecrackers and a police weapon being loaded.
