One of the Brussels airport bombers was freed from custody in Europe despite Turkey warning he was a "foreign fighter", the Turkish president has claimed.
Ibrahim El Bakraoui was detained in the Turkish city of Gaziantep last June near the Syrian border and then deported to the Netherlands a month later at his own request, said Recep Tayyip Erdogan.
The Turkish leader said Belgian consular authorities were told about his deportation in July.
But El Bakraoui was later freed as Belgian authorities “ignored our warning that this person is a foreign fighter”, said Mr Erdogan, without saying when.
The president’s office later said he was released as “no links with terrorism” were found by Belgian officials.
Turkey also warned Dutch authorities, Mr Erdogan said. A Dutch government official says the president’s remarks are being investigated, while Belgian officials have not responded to the claims.
