Ankara: Turkey said Wednesday it had detained and then deported Ibrahim El Bakraoui, one of the two suicide bombers at Brussels airport, and accused the Belgian authorities of failing to confirm his links to terror.
President Recep Tayyip Erdogan said Turkish authorities detained the attacker in June last year in Gaziantep, close to the Syrian border, and then deported the "foreign terrorist fighter" to the Netherlands at his request.
A Turkish official confirmed to AFP that the attacker in question was 30-year-old Ibrahim El Bakraoui, a Belgian citizen who was one of the two suicide bombers who blew themselves up at Brussels airport on Tuesday.
Belgian Justice Minister Koen Geens said he was aware that the man had been sent to the Netherlands from Turkey, but denied that he had been flagged as a possible terrorist.
Erdogan however said the Belgian authorities had failed to confirm the suspect's links to terrorism "despite our warnings" following his deportation.
He said Belgian consular authorities were formally notified of his deportation on 14 July, 2015, adding that he was then released by the Belgian authorities, without giving a timeframe.
"Despite our warnings that this person was a foreign terrorist fighter, the Belgian authorities could not identify a link to terrorism," he told reporters in Ankara.
Erdogan said the man had initially been deported to the Netherlands at his own request and that Dutch as well as Belgian authorities had been informed.
He did not specify how he had been transferred from the Netherlands to Belgium, where 31 people died in the bomb attacks at the capital's airport and on a metro train.
Geens said Belgian federal prosecutors told him the suspect was stopped at the Turkey-Syrian border and sent to the Netherlands.
"At that time, he was not known here for terrorism," he told Belgium's VRT television. "He was a common law criminal out on parole."
Erdogan meanwhile called for more international cooperation in the fight against terror.
"I believe that we can work this out if world leaders form an alliance against terror. For that, we need to redefine global terror and terrorists," Erdogan said.
Turkey has previously complained that Western countries did not heed warnings of the dangers posed by jihadists it had expelled back to Europe after arresting them on the Syrian border.
European officials have also urged Turkey to improve intelligence sharing and praised an increase in cooperation in recent months.
Turkey says it alerted France on two occasions that one of the assailants in the Paris attacks was a potential threat after he travelled to the country in 2013, likely on his way to Syria. But officials say they never received a response from Paris.
Turkey's European affairs minister Volkan Bozkir on Wednesday said a total of 3,128 suspected foreign jihadists had been expelled from the country since 2011.
In Tuesday's coordinated bombings in Brussels, Bakraoui's brother Khalid, 27, also blew himself up, in an attack at the Maalbeek metro station in the heart of the European district in Brussels.
