Officials announced Saturday it would take more time than expected to reopen Brussels Airport after suicide bombers struck in the facility's departure hall on Tuesday.

Airport authorities said passenger flights would not resume until this coming Tuesday at the earliest.

In a news release, the airport said it is working to implement new security measures in the wake of the March 22 attacks on Brussels that claimed 31 lives. A team of engineers and technicians still needed to asses the damage left by the explosions at the airport and determine what the process will be to renovate the terminal.

“Except for authorized staff, nobody will be admitted to the area where the explosions occurred,” airport officials said. “The federal police and the security agents continue to carry out stringent identity checks in the access area to the airport.”

Brussels Airport was one of two locations targeted by suicide bombers in attacks on Brussels. Bombings at the airport and the Maelbeek Metro train station claimed 31 lives and injured 270 others.
