2 brothers identified as Brussels attackers; 3rd suspect sought

BRUSSELS — Belgians began three days of mourning Wednesday for the victims of the Brussels airport and subway bombings, and the country remained on high alert as authorities hunted for one of the suspected attackers seen on surveillance video with two others who blew themselves up.

Turkish authorities, meanwhile, said they had caught one of the suicide bombers near the Turkish-Syrian border in July and sent him back to the Netherlands, warning both that country and Belgium that he was a “foreign terrorist fighter.”

Several people who may be linked to the attacks were still on the loose and the country’s threat alert remained at its highest level, meaning there is danger of an imminent attack, said Paul Van Tigchelt, head of Belgium’s terrorism threat body.

A taxi driver who took Ibrahim El Bakraoui and two others to the airport led investigators to an apartment where they found 33 pounds of TATP explosives, along with nails and other materials used to make bombs, Van Leeuw said.
