A week after devastating suicide bomb attacks, Brussels Airport will test its capacity to partially resume passenger service. But it's too early to say when service might actually resume, an airport official said Monday.

Florence Muls, the airport's external communications manager, said 800 staff members on Tuesday will test temporary infrastructure and new arrangements designed for passenger check-in. The Belgian government must approve the new system, Muls said, before Brussels Airport can resume handling passenger traffic.

Two suicide bombers on March 22 caused great damage to the airport's departure hall, and along with another suicide bomber who blew himself up on a Brussels subway train, killed at least 31 people and injured some 270.
