Short but wild vid. Appears between gangs as they didn’t pay any attention to the people around them, so clearly not just shooting targets of opportunity. Note sparking around them also, so someone was returning the favor:
"Belgian police are looking for armed men after a shooting was reported outside a metro station in the centre of Brussels.
CCTV footage broadcast by local media shows at least two men wearing balaclavas and carrying weapons at the entrance of Clémenceau station in the Belgian capital early on Wednesday.
Video from the scene shows an exchange of fire at about 06:15 local time (05:15 GMT).
Sarah Frederickx, spokeswoman for Brussels police, said the suspects may have fled into the tunnels of the metro system."
