“Solid-fuel missiles can be set up and fired faster than those containing liquid fuel. That’s a key concern for the Houthis as their missile launch sites have been repeatedly targeted by U.S. and allied forces in recent months over the rebels’ attacks on shipping through the Red Sea corridor. One such strike hit the Houthis even before they were able to launch their missile.
For their part, the Houthis described the Palestine as a “locally made” missile. However, the Houthis are not known to possess the ability to manufacture complicated missile and guidance systems locally in Yemen, the Arab world’s poorest country, which been gripped by war since the rebels seized the capital, Sanaa, nearly a decade ago.
The Houthis have, however, been repeatedly armed by Iran during the war despite a United Nations arms embargo. While Iran claims it doesn’t arm the Houthis, ships seized by the U.S. and its allies have found Iranian weaponry, missile fuel and components on board.
Iranian media reported the launch of the Palestine and described it as locally manufactured, citing the Houthis. However, design elements on the missile resemble other missiles developed by Iran’s paramilitary Revolutionary Guard. That includes one called the Fattah, or “Conqueror” in Farsi.”
