At least one of the two Brussels Airport terrorist attacks was carried out by a suicide bomber, Belgian Federal Prosecutor Frederic Van Leeuw said in a press briefing on Tuesday.
"There were two explosions at a departure hall in Zaventem this morning. One was possibly arranged by a suicide bomber," Leeuw said as media reports emerged of up to 28 deaths.
Leeuw said a third explosion at the Malbeek subway station in central Brussels occurred half an hour after the initial blast.
The blasts in Brussels come just days after Salah Abdeslam, the mastermind behind the November Paris Attacks, was arrested in Belgium.
