A Brussels police commissioner was drunk and ineffectual at a crisis meeting following last week's terror attacks in Brussels, local media reported on Wednesday.

The newspaper La Derniere Heure reported that the meeting on the evening of the attacks was held to discuss pressing issues, decide on where to increase surveillance and examine police staff levels.

A police spokesperson confirmed an inquiry was being conducted but declined to provide details.

Belgian police have been under criticism since their failure to find and arrest so-called "Islamic State" (IS) extremists following the November Paris attacks.

Three suicide bombers carried out the March 22 attacks on Brussel's airport and the Maelbeek metro station, killing 32 people. The attack was subsequently claimed by IS.
