TEHRAN (Reuters) - A U.S. airliner flying from Bombay to Amsterdam made an emergency landing in Tehran on Sunday, but no one was hurt and the plane continued its journey after repairs, a civil aviation official said. The United States and Iran have been on hostile terms since the 1979 Islamic revolution.

The Northwest Airlines flight landed at 4 a.m. (2330 GMT, Saturday) at Tehran's Mehrabad airport after encountering a technical problem with its cargo section, Mohammad Jafarzadeh, spokesman for Iran's Civil Aviation Organization, said.

"All 255 passengers and crew are safe and sound and were taken to the airport transit lounge," he said.

After repairs, the airliner left with all its passengers for Amsterdam at 11:10 a.m. (0640 GMT), Jafarzadeh said later.

There are no air links between Iran and the United States. U.S. military planes flew relief supplies to the southern city of Bam after a devastating 2003 earthquake.
