Iraq wants to buy about 100 mobile Scud missile launchers from Iran, an intelligence official says.

The request, along with the flight of 90 Iraqi planes to Iran, has military officials perplexed.U.S. officials don't know if Iran is willing to sell the launchers, which it bought from North Korea in the 1980s, "but there are suspicions," the source, speaking on condition of anonymity, said Tuesday.

Asked about the report, Iran's ambassador to the United Nations, Kamal Kharrazi, said Wednesday that speculation about Scud launcher sales to Iraq was "baseless." He did not elaborate.
