The shooting took place in the Hoevestraat in the early afternoon, the Brussels judicial authorities stated. A row between Chechen and Russian community members apparently ran out of hand.
No suspects have been apprehended yet. The Hoevestraat was sealed off for a certain time. Police are looking at CCTV footage, and a helicopter was being deployed to boost the search. Sint-Joost Mayor Emir Kir said eye witnesses made videos of the incident; this footage was handed over to investigators.
