BRUSSELS (AFP) - Brussels airport will remain closed until at least Saturday, a spokeswoman said, following deadly bombings claimed by the Islamic State in Iraq and Syria (ISIS) group.

"The airport is closed to passengers until Friday included," spokeswoman Anke Fransen told AFP on Wednesday, a day after the attacks by two suicide bombers that wrecked the departure hall.

"We cannot say for certain if the flights will be reopened to passengers on Saturday," she said, adding however that cargo and private flights could resume "as of now".
