UPDATE 1-Hungary detains Syrian Islamic State member accused of killings -prosecutors

Hungarian authorities have detained a Syrian man on Friday accused of taking part in beheadings in Syria as a member of Islamic State, Budapest prosecutors said in a statement.

The man, not identified in the statement, is suspected of executing about 20 people in 2016, all family members of a person in Homs city who refused to join Islamic State, the prosecutors said. The statement said the man, prior to being detained, was already awaiting deportation to Greece.

He had been caught with forged documents in Budapest's main airport on Dec. 30 last year, given a suspended prison sentence for human trafficking and other crimes, and ordered expelled from Hungary. Eurojust, the European agency that oversees judicial co-operation in crime investigations, working with Belgian and Hungarian authorities, found evidence later that he was an Islamic State member, the prosecutors said.
