The explosion was approved by the city's authorities.
"We've received confirmation. There was an explosion on Louise Avenue, but we're talking about the work of the bomb disposal techs. They blew up a suspicious object. We're not talking about a new attack. The specialists have cleaned the area near Maalbeek metro station," the RTBF correspondent reports.
A series of blasts hit the Belgian capital earlier in the day, including two explosions in the Brussels Zaventem airport that left 13 people killed and 35 injured. Ten people were reportedly killed in explosions at the Maalbeek and Schuman metro stations in central Brussels, local media reported, citing police.
