French police have arrested a 29-year-old man suspected of being involved in the shooting deaths last weekend of three people at Brussels' Jewish Museum, official sources in Belgium and France said on Sunday.
The Frenchman was arrested in the southern French city of Marseilles on Friday and had a Kalashnikov and another gun with him, a French police source said.
The man, from the northern city of Roubaix, had been in jail in 2012.
