Hezbollah has been using a reverse-engineered copy of an Israeli missile against Israel, according to Israeli defence officials. The group seized the original Israeli Spike anti-tank missiles during the 2006 war and sent them to Iran for cloning. The rebranded Almas missiles have a range of up to 10 miles and carry advanced guidance seekers. The use of Iranian-engineered weapons is said to be fundamentally altering regional power dynamics.
