Brussels: One of the suicide bombers who attacked Brussels airport on March 22 had worked as a cleaner in the offices of the European Parliament.

The man "held a summer holiday job cleaning at the Parliament" in 2009 and again in 2010, a EU statement quoted by Agence France-Presse said. While it did not name the man, AFP learnt it was Najim Laachraoui who is also suspected of being the maker of bombs used in the November 13 attacks in Paris.

The revelation comes two weeks after Islamic State claimed responsibility for the attacks which killed 32 people at the airport and at a train station in Brussels, and a week after it was revealed a file with the floor plan and photographs of the office of the Belgian prime minister was found on a laptop discarded by one of the terrorists linked to the attacks.
