REYKJAVIK — An Aeroflot plane carrying 256 people from New York to Moscow made an unscheduled landing in Iceland on Thursday following a report of a bomb on board, authorities said. The plane, an Airbus A330, landed at Iceland's Keflavik International Airport where baggage and passengers were being inspected as part of the search for explosives. Russia's ITAR-Tass news agency quoted Aeroflot spokeswoman Irina Dannenberg as saying the bomb warning came from an anonymous caller to New York City police after the plane took off. A law enforcement official with knowledge of the investigation said an anonymous call was placed to authorities in New York about 90 minutes into the flight. The official did not know the language of the threat but said it referred to explosives on the plane. — AP
