Brussels, the largest city in Belgium and the seat of the European Union, was in lockdown Tuesday after a series of explosions rocked the city’s international airport and a central subway station. More than 30 people were killed in the blasts, for which ISIS, the Islamist militant group based in Syria and Iraq, took responsibility.
Lawyers at major firms in Brussels described huddling in their offices and conference centers, heeding warnings by local law enforcement authorities to “avoid all movement” in case of future bombings.
