Not clear whether launch of ICBM by Iran was for satellite: US intel sources

American intelligence sources said Sunday they are not sure that Iran's April 19 launch of its new "Simorgh" intercontinental ballistic missile was for putting a satellite into orbit, as Tehran claims. They said it may have been intended to test the third stage of the ICBM and that the Iranians had no intention of launching a satellite. 
US defense officials were earlier quoted as saying American intelligence services view the launch as a partial success although the missile did not reach orbit. The Simorgh is considered to be a main part of Iran's long-range missile development program.
