The Belgium police arrested some persons suspected of involvement in the bombings in Brussels on Tuesday, which claimed at least 30 lives, according to Belgian newspaper DH on its website.
Najim Laahraui came in the focus of the cameras, when along with two alleged bombers was pushing a cart with luggage at the airport of Brussels. In addition to the airport, the explosions sounded in the metro.
After the explosions, at the airport there was found an unexploded bomb and an unknown man was observed running out of the terminal immediately after the incident.
Earlier DH reported, with reference to the prosecutor's office, that Laahraui DNA was found in houses used by the organizers of attacks in Paris last year that claimed 130 lives.
According to the newspaper, in September Laahraui traveled to Hungary together with Salah Abdeslamom - the organizer of the Paris attacks, arrested last week.
Abdeslam was caught after a police operation in one of the apartments in Brussels, which was allegedly hired by one of the two suicide bombers who blew themselves up at the airport on Tuesday. In the apartment there were found the ISIS flag and explosives.
According to RTBF television channel, the bombers were residents of Brussels - brothers Khalid and Brahim El Bakraui, who were already known to the police as they previously violated the law.
The responsibility for the bombings was claimed by ISIS.
After the attacks, the Brussels police carried out an operation in the north of the city finding another explosive device, the ISIS flag and chemicals that could be used for the manufacture of explosives.
According to local media, the police received information from the taxi driver who believes that the alleged bombers drove to the airport.
