Belgian authorities have carried out another search and arrest in the investigation into the suicide bombings that killed 32 at Brussels Airport and the city's subway in March.

The Federal Prosecutor's Office on Friday said an apartment in the Schaerbeek area of Brussels was searched the previous day and a man detained and charged with participation in the activities of a terrorist group, terrorist murder and attempted terrorist murder.

The 31-year-old Belgian national was identified only as Ali E.H.A.

The bombers who attacked the airport took a taxi to their target from Schaerbeek, with their bombs hidden in suitcases.

Prosecutors said no further information would be divulged so as not to hamper the investigation of the March 22 attacks, which were claimed by the Islamic State group.
