Police have launched a frantic search in Brussels for an ISIS terrorist suspected to have the airport bombings Tuesday morning. Raids have been launched around the city, including one that turned up an explosive device, chemicals and an ISIS flag, Belgian prosecutors said.

Three of the suspects involved in the deadly bombings at Brussels Airport were seen on a surveillance camera before the terror attacks, according to Belgian media reports. Nails and other shrapnel were found in bombs detonated Tuesday.

According to DH.be, the two men on the left in the photo were killed in the bombings. They have been identified by Belgian media as brothers Khalid and Brahim El Bakraoui.

The third man, on the right, is actively being sought by authorities. Belgian media has named him as 24-year-old Najim Laachraoui, a suspected ISIS bombmaker who was already wanted by police for his alleged role in the November 2015 Paris attacks.

Authorities tweeted the photo with the caption “Who recognizes this man?”

At least 34 people were killed and more than 170 were wounded in explosions at the airport and in a subway in the capital of Belgium, CNN reports. ISIS has claimed responsibility for the attacks.

There have been multiple raids launched by authorities in Belgium as police search for the suspect and others possibly tied to the attack.

One of the lead members of the ISIS cell that attacked Paris in November 2015 was recently arrested in Belgium. Salah Abdeslam was taken into custody during a raid in Molenbeek last week.
