A new suspect has been arrested on accusations of “terrorist murders” during Isis’s Brussels attacks as security services continue attempts to root out a European network of jihadists.

The man, named as 31-year-old Ali E H A by Belgium’s federal prosecutor, was detained during a raid on a home in the suburb of Schaerbeek – the district where the three bombers prepared for their attack on 22 March.

He has been arrested on suspicion of participation in the activities of a terrorist group, terrorist murders and attempted terrorist murders.

Authorities did not stipulate whether he was as a perpetrator or accomplice in the bombings at Brussels Airport and Maelbeek Metro station and said no further information would be given.
