Iran has unveiled two new missiles amid heightened tensions between Iran and the United States, reported Iran State TV.   State TV said officials unveiled the two new missiles on Thursday — National Defense Industry Day in Iran, reports AP.   They are named after top Iranian Gen. Qassem Soleimani and Iraqi militia leader Abu Mahdi al-Muhandis, who were killed outside Baghdad’s international airport in a U.S. strike in January.   The “Martyr Hajj Qassem” surface-to-surface ballistic missile has a 1,400-kilometer (870-mile) range, according to the semi-official Fars news agency. State TV said the “Martyr Abu Mahdi” naval cruise missile has a 1,000-kilometer (620-mile) range.   State TV said the “Martyr Hajj Qassem” missile was not intercepted by a defense system during a test.   Also on Thursday, Iran unveiled a fourth-generation light turbo-fan engine for its advanced drones.   Iran also inaugurated the production line of its domestically produced “Owj” engine for the Iranian-made twin-seat Kowsar fighter jet.   Iran routinely unveils technological achievements for its armed forces, its space program and its nuclear efforts.   President Donald Trump pulled the U.S. out of the nuclear agreement between Iran and six major powers, known in 2018, and tensions between the two countries have escalated since.   Also read: N Korea fires missiles off its east coast, says S Korea
