BRUSSELS—Belgians began three days of mourning Wednesday for the victims of the Brussels airport and subway bombings, and the country remained on high alert as authorities hunted for one of the suspected attackers seen on surveillance video with two others who blew themselves up.
Several people who may be linked to the attacks were still on the loose and the country’s threat alert remained at its highest level, meaning there was danger of an imminent attack, said Paul Van Tigchelt, head of Belgium’s terrorism threat body. The attacks killed 34 people, including three suicide bombers, and injured 270 others, authorities said.
As government offices, schools and residents held a moment of silence Wednesday morning to honor the dead, the mood was defiance mixed with anxiety that others involved in the attacks are still at large.
