Erdogan’s office later identified the man as Ibrahim El Bakraoui, one of the two brothers named by Belgium as responsible for the attacks that killed at least 31 people in Brussels on Tuesday and were claimed by the Islamic State group.
Speaking at a news conference, Erdogan said Bakraoui was detained in the southern Turkish province of Gaziantep near the Syrian border and was later deported to the Netherlands. Turkey also notified Dutch authorities, Erdogan said.
“One of the attackers in Brussels is an individual we detained in Gaziantep in June 2015 and deported. We reported the deportation to the Belgian Embassy in Ankara on July 14, 2015, but he was later set free,” Erdogan said.
“Belgium ignored our warning that this person is a foreign fighter.”
Erdogan’s office confirmed that Bakraoui was deported to the Netherlands. It said he was later released by Belgian authorities as “no links with terrorism” were found. It was not clear when Bakraoui was handed over to Belgian authorities.
Erdogan initially said Bakraoui was deported in June but his office later said he was detained in June and deported in July.
The attacks in Brussels came just days after a suspected suicide bomber blew himself up in Istanbul’s most popular shopping district, killing three Israelis and an Iranian and wounding dozens more people.
