Belgian media reported that a 28-year-old Syrian, who entered the EU as a refugee, is one of the people involved in the attacks which occurred on March 22 in Brussels.

In September of last year he arrived on a Greek island with a boat which carried some of the perpetrators of the Paris attacks that occurred in November of last year. His true identity still has not been revealed and he is only known by his fake name. His fingerprints were discovered at the apartment where the bombs used in the Brussels explosions were prepared.

The police have a picture of the suspect and it is assumed that he is the 'man with the hat' from the Brussels airport footages.

The airport is now closed and it is still uncertain when flights will resume. The Brussels metro is partially open, with 30 out of 69 stations in operation.
