Ok, found some French articles.
They are “evidently” considering antisemitism and they are calling this terrorism. They have one of the two,suspects and have interrogated him or her - they don’t say which gender (”personne” is feminine no matter whom you speak about). They Aren’t telling whether they caught the shooter or the one who was with the double parked car.
The shooter shot the three dead and the one gravely injured in the face and throat repeatedly.
FYI
Two of the Brussels shooting victims confirmed Israeli citizens
The couple, tourists in their 50s from Tel Aviv, were not carrying any identifying documents; a fourth victim died of his wounds overnight.
