Belgian prosecutors say 'chemical products,' Islamic State group flag found in raid
A Belgian prosecutor says police raids are happening around the country after two men "probably" staged suicide bombings at the Brussels airport and a third fled.
Prosecutor Frederic Van Leeuw said Tuesday that the third suspect is actively being sought by police.
Belgian federal prosecutors say a house search in the Brussels neighborhood of Schaerbeek has "led to the discovery of an explosive device containing among other things nails."
Investigators also found chemical products and an Islamic State flag.
At least 31 people were killed and nearly 190 wounded in the two airport bombings and another in the Brussels subway system.
Prime Minister Charles Michel said the country will tighten security at its borders. He declared three days of national mourning after what he says were probably the most tragic attacks the country has seen in peacetime.
Federal police in Belgium have issued a wanted notice for a suspect in the Brussels airport bombing that they are still trying to identify.
A man wearing a thick light-colored jacket with a black hat and glasses is suspected of committing an attack at Zaventem airport on Tuesday morning.
They are urging the public to call them if they recognize the man.
