Belgium's transport minister has resigned over her alleged failure to respond to a report on security shortcomings at Brussels Airport prior to last month's suicide bombings.

Jacqueline Galant reportedly handed her resignation in on 15 April, after a week of speculation during which she was accused of lying about an EU report that criticised security at the airport.

Galant had stated she was unaware of the report, which highlighted key security lapses ahead of the attacks on 22 March, when three suicide bombers from Islamic State (Isis) detonated bombs at the airport and a metro station, killing 32 people.

Galant's resignation came just one day after a top transport civil servant, Laurent Ledoux, handed in his resignation, stating he requested funds to look into airport security more than a month before the terror attacks, but had been refused.

His resignation also mentioned the security report that was carried out in 2015, and has been leaked by the opposition party, which the FT said referenced the airport's failure to use bomb-detecting dogs.
