A firebomb attack on a Shi'ite Muslim mosque in Brussels that killed a popular local imam triggered an anti-terrorist investigation on Wednesday, but police remained uncertain of the detained suspect's identity and local Muslims baffled about his motives.
Prosecutors have released few details about the suspect, a man in his 30s who locals said entered the mosque in a rundown quarter of the city shortly after evening prayers on Monday carrying an axe, a knife and a can of petrol, which he poured over the prayer mats and ignited.
"He is saying he is a Salafi Muslim," federal prosecutor Leen Nuyts told Reuters, adding that it was one of several explanations he had offered. "He is saying that Syria could have played a part, but we have to do further investigation" before reaching that conclusion, she said.
