Brussels: Brussels airport police say they criticised security at Belgium's main transport hub well ahead of the March 22 attacks.
Two suicide bombers blew themselves up in the departure hall, wrecking the concourse, and shortly afterwards another bomber hit the Brussels metro, leaving 35 people dead in Belgium's worst-ever terror attack.
In an open letter to their superiors and the airport authorities that they provided to The Associated Press on Thursday, police said they had sent "strong daily signals regarding the overall security at the airport."
They complained that "there had not been any security control of passengers or luggage from the airport complex right up to the centralised body searches" area.
The letter said the lack of security was such that police fear "scouts were sent out to assess the security lapses and plan terror."
The airport police also complain that too many airport employees have criminal backgrounds....
