“We were fearing terrorist attacks, and that has now happened,” Belgian Prime Minister Charles Michel told reporters.

Belgian federal Prosecutor Frederic Van Leeuw said it was too soon to know exactly how many people died in the bombings. Yet the Brussels Metro Authority reported that 15 died and 55 were wounded in the subway station blast. And public broadcaster VRT said at least 13 more were killed, and about 35 were injured, in the two blasts in the Brussels airport departure hall.

Of the two explosions at the airport, at least one was a suicide bombing, Van Leeuw said. A blast happened there outside the security checkpoints for ticketed passengers and near the airline check-in counters, an airline official briefed on the situation said.
