So far Yemen was mainly executing a sea blockade on Israel according to international law specially after the International Criminal Court found Israel guilty of committing genocide in Gaza.
That blockade has been working very well. No ship belonging to or heading to the Zionist terrorists were allowed to enter the Gulf of Aden and Red Sea for the past 1.5 years. Which is why US regime started the terrorist attacks against Yemen (in previous administration, something Trump is just following without any results).

The Armed Forces of Yemen recently announced that they plan on enforcing an "air blockade" on Israel from now on as well. In other words a no fly zone over occupied Palestine as long as Israel continues murdering unarmed civilians in Gaza in an act of genocide.
All the Zionist airbases are going to be hit, the military strike on al-Lod airbase (the gif above) was part of that operation.
