Brussels: At least two Brussels attackers may still be on the run in Belgium as police continue to hunt for accomplices.
A suspect caught on CCTV pushing a luggage trolley next to two suicide bombers at Brussels Airport is believed to have survived and fled the scene, leaving his unexploded suitcase bomb sitting in the departures hall.
Searches have been underway for the unidentified man since the attacks on Tuesday but a fifth suspect may also have been involved, according to new reports.
Before Khalid el-Bakraoui blew himself up at Maelbeek Metro station, another man was spotted carrying a large bag on surveillance cameras.
Belgium’s public broadcaster, RTBF, quoted security sources saying he was suspected of involvement but had not been identified, adding that it was unclear whether the man had died or escaped before the blast.
Prosecutors did not immediately confirm the reports.
El-Bakraoui’s brother, Brahim, was identified as one of two suicide bombers who targeted the Brussels Airport the same day in attacks that killed at least 31 people and injuring around 300.
The second dead airport attacker was Najim Laachraoui, a veteran Belgian Islamist fighter in Syria suspected of making explosive belts for November’s Paris attacks.
He was originally reported to be on the run, with police releasing the 24-year-old’s mugshot and appealing for information on him and his alias, Soufiane Kayal.
Maggie De Block, the Belgian health minister, said around 60 victims were still in intensive care on Wednesday, including four in a coma.
Efforts are continuing to identify the wounded and killed, who are from more than 40 countries, as families continue desperate appeals for information.
