Updated at 7:01 a.m. ET: A passenger jet flying from New York to Moscow made an emergency landing in Iceland on Thursday after a caller claimed there was a bomb on board, a spokeswoman for Russian airline Aeroflot said.

Fridthor Eydal, the manager at Reykjavik's Keflavik International Airport, told NBC News the Airbus A330 with 253 passengers on board landed safely at 6:27 a.m. (2:27 a.m. ET) and the plane had been evacuated.

"There was an anonymous call saying that there was an explosive device on the plane, which was already in the air," spokesman Irina Dannenberg said.

The call was made to the New York City police, Dannenberg told the ITAR-Tass news agency.

Passengers were going through standard security procedures on the ground in Reykjavik and would later be transported to a nearby hotel, local police told NBC News.

Police planned to search the aircraft later Thursday, authorities said.

Second plane searched
Emergency teams also searched an airplane in the city of Voronezh, 300 miles south of Moscow, for explosives on Thursday after an anonymous phone call was made to the city's airport, but no bomb was found, state-run RIA reported.

A suicide bomb blast in the international arrivals area at Moscow's Domodedovo airport in January 2011 killed 37 people. Islamist insurgents in Russia's North Caucasus claimed responsibility.

Suicide bombers identified as women from the North Caucasus blew up two planes on domestic Russian flights nearly simultaneously in August 2004, killing all 90 people aboard.
