Scores have been killed and wounded after explosions tore through Brussels airport and a metro station in the centre of the city.
Reports from Kurdish media said the terror group had admitted being behind today’s strike.
Security experts and a leading European government minister have also suggested ISIS are to blame for the Brussels atrocity.
Today’s multiple blasts come just days after the arrest of Salah Abdeslam in the Molenbeek district of the Belgian capital.
Experts are now warning that today’s terror attacks could be a revenge strike after the suspected Paris massacre mastermind was detained in a dramatic police raid in which he was shot in the leg.
