A group of Turkish youths threatened to kill a Catholic friar, grabbing him by the throat and shouting "God is Greatest," just days after a Catholic priest was shot dead in Turkey, the friar said Friday. Martin Kmetec, a Franciscan friar from Slovenia, opened the door of his house on Thursday to find seven or eight angry men in their 20s. "He took me by the throat and pulled me inside and said 'we're going to finish you off' ... he also said Allahu Akbar (Arabic for God is Greatest)," Kmetec told Reuters by telephone from his church in the province of Izmir.Kmetec closed the door on the youths, who said they were nationalists, but left after trying to break the door down. A local police spokesman said they were investigating the matter.
