A Marine reservist was charged with attacking a Greek Orthodox priest he said he thought was a terrorist. The reservist, Lance Cpl. Jasen D. Bruce, is accused of hitting the Rev. Alexios Marakis over the head with a tire iron and chasing him for three blocks on Monday evening before Tampa police officers intervened. Father Marakis, a Greek Orthodox priest visiting from Crete, told the police he had stopped to ask for help after getting lost. Mr. Bruce told the police he heard Father Marakis yell, “Allahu akbar!”  Arabic for “God is great,” said a police spokeswoman, Laura McElroy. Father Marakis, however, does not speak Arabic, Ms. McElroy said; he speaks Greek. Lance Corporal Bruce’s lawyer said his client was the one attacked.
