A mosque near Brussels has been targeted in an arson attack in which the imam died.
A Muslim man was arrested in the attack on the mosque in Anderlecht, a suburb of Brussels, the Belgian capital, said Jean-Marc Meilleur, a spokesman for the Brussels Prosecutor's Office.
"It seemed that this person showed up and pulled out a knife and an axe, and that he spread flammable products - petrol, we assume - in order to start a fire and threaten the mosque occupants," Mr Meilleur said.
The attacker was shouting anti-Shiite Salafist slogans about the conflict in Syria.
Isabelle Praile of the Muslim Executive, herself a Shiite, told RTBF that the Rida mosque, the biggest mosque in Brussels, has been guarded by the police for years after threats by Salafists.
