Iran is ready to share its missile systems with friends and neighbors, the commander of the Revolutionary Guards said, after he showed off missiles including some he said had cluster warheads.

Guards commander-in-chief Yahya Rahim Safavi also told Iran's Arabic-language Al-Alam TV late on Sunday the Guards had thousands of troops trained for suicide missions in case Iran was threatened although he said any U.S. attack was unlikely.

"We are able to give our missile systems to friendly and neighboring countries," Safavi told Al-Alam. A text of his comments in Farsi were obtained by Reuters on Monday.

Iran's ambassador to Lebanon, Mohammad Reza Sheibani, was quoted by Iran's semi-official Mehr News Agency on Sunday as saying the Islamic Republic was ready to supply air defense systems -- without giving specifics -- to the Lebanese military.

"Tehran also considers this as its duty to help friendly countries which are exposed to invasion of the Zionist regime (Israel)," Sheibani was quoted saying, in response to what he said was a request by Lebanon's army commander, General Michel Suleiman, for help from friendly states.

Military experts said the exercises were to show off Iranian technology, although they say many systems are based on modified versions of equipment from other countries, such as North Korea.
