Belgian police investigating the Brussels airport and metro attacks have arrested a man in connection with "terrorist murders", the federal prosecutor said on Friday. The 31-year-old man, identified only as Ali E.H.A., was detained on Thursday during a house search in the Schaerbeek area of the capital, the prosecutor's office said. Several people have previously been charged over the March 22 suicide bombings at Zaventem airport and Maalbeek metro station which killed 32 people. "In connection with the federal investigation after the terrorist attacks in Zaventem and Brussels, a house search was conducted," the statement said.
