A Frenchman with suspected ties to Islamic radicals in Syria has been arrested over last week's shooting at the Jewish Museum in Brussels that left four people dead, investigation sources told AFP on Sunday.

The suspect, 29-year-old Mehdi Nemmouche, was arrested Friday in the southern French city of Marseille in possession of a Kalashnikov rifle and a handgun similar to the ones used in the attack on May 24, the sources said.

He has been detained on suspicion of murder and attempted murder in connection with a terrorist enterprise, a judicial source said.
