Najim Laachraoui

Belgian police arrested six people in the Brussels suburb of Schaerbeek on Thursday as the manhunt for suspects in Tuesday's terrorist attacks targeting Zaventem airport and Maelbeek metro station continues.

It is still unclear whether the arrested people are connected to the attacks and their identities have not been revealed yet.

Belgian newspaper DH reports that the third bombing suspect who fled the airport on Monday, Najim Laachraoui, has been arrested in Anderlecht.

The man shown at the photo below standing next to the two arrested attackers and wearing a hat is Nazim Lachraoui. The Belgian authorities arrested him on

Wednesday morning at a pizza restaurant, after launching a manhunt.

The Belgian authorities confirmed that brothers Khalid and Brahim El Bakraoui are among Brussels Airport suicide bombers.

According to Belgian broadcaster RTBF, the brothers were known to police for links to organized crime.

In the meantime, authorities have released a manhunt to find the third attacker.

According to media reports, the two suicide bombers, who blew themselves at Zaventem airport on Tuesday, have been identified as brothers Khalid and Brahim el-Bakraoui.

The el-Bakraoui brothers have been well-known to police and have reportedly been sought for hiring properties as hideouts for the perpetrators of last year's attacks in Paris.

A photograph of the two suspects involved in terrorist attack at the Saventem airport in Brussels was released just before they detonated the explosives. Belgian network DH released the photo it got from the airport closed security cameras showing the two suspect terrorists seconds before they activated the bombs.

Two suspected terrorists are likely to be the focus of investigations for the deadly attacks occurred on Thursday at Brussel’s airports and metros.

Najim Laachraoui and Mohamed Abrini named by Belgian police as accomplices to November’s Paris attacks are still on the run after police raids that led to the arrest of Salah Abdeslam, the lead Paris attacker, on Friday.

The prime surviving suspect in the Paris attacks may have been plotting more operations with the help of a weapons cache and a network of associates, Belgium's Foreign Minister Didier Reynders said on March 20.
