Police raids are happening around Belgium after two men "probably" staged suicide bombings at Brussels airport and a third fled, a Belgian prosecutor said.
Prosecutor Frederic Van Leeuw said that the third suspect is actively being sought by police.
At least 31 people were killed and nearly 190 wounded in the two airport bombings and another in the Brussels subway system.
Belgian Prosecutor Eric van der Sypt said two bombers died at Brussels airport and a third is being "actively" sought.
Belgian police have released CCTV footage of three men suspected of carrying out the attack on the airport.
The photo shows three unidentified men pushing trollies with suitcases in Zaventem airport's terminal building, two of whom are wearing a black glove on their left hand.
Belgian police have released the image as part of their investigation, according to the Belgian news agency Belga and local newspaper La Libre.
Prime Minister Charles Michel said the country will tighten security at its borders. He declared three days of national mourning after what he says were probably the most tragic attacks the country has seen in peacetime.
