An Islamic State flag was found by the body of a gunman shot in a house raid near Brussels, authorities said.
Two suspects escaped during the anti-terrorism raid, which was linked to the Paris attacks.
One gunman killed during an operation in Brussels linked to November's Paris terror attacks was holding a Kalashnikov assault rifle at the time, the Belgian federal prosecutor has revealed.
In a statement, the prosecutor's office said when officers approached the apartment to search it, "one or more people immediately opened fire on police the moment the door was opened by the security forces."
Around five hours later, police stormed the building again and "a suspect armed with a Kalashnikov was killed".
Earlier reports said the suspect was spotted in a garden near the apartment block, and had been shot by a sniper.
