Police in Belgium have released a surveillance photo of the suspected terrorists who detonated bombs that killed 31 and injured nearly 200 at a European airport Tuesday morning.
The photo was taken at the Brussels airport before the attacks.
At least one of the airport blasts was attributed to a suicide bomber. The Islamic State group claimed responsibility for the carnage.
In the photo, three men are seen strolling through the Zaventem terminal, pushing luggage carts.
ABC News reported that two of the men may be dead and authorities were searching for the man in the hat.
Windows were blown out, ceilings collapsed and smoke poured through the building.
An hour after the airport blasts, a bomb went off in the subway. Another bomb was found at the airport and deactivated by authorities.
“We are at war,” French Prime Minister Manuel Valls said after a crisis meeting in Paris.
“We have been subjected for the last few months in Europe to acts of war.”
European security officials have been bracing for a major attack for weeks, and warned that the Islamic State group was actively preparing to strike.
The arrest Friday of a key suspect in the November attacks in Paris heightened those fears, as investigators said many more people were involved than originally thought, and that some are still on the loose.
