Israeli fighter jets bombarded the main international airport in the Yemeni capital of Sana on Tuesday, the Israeli military said, two days after the Houthi militia in Yemen fired a ballistic missile that struck near Israel’s main airport.

The Israeli attack was the latest salvo in an ongoing battle with the Iran-backed Houthis, who rule Sana and much of northwestern Yemen. They have fired scores of rockets and drones at Israel in what they call a solidarity campaign with Palestinians to press for an end to the war in Gaza.

The scope of the damage to Sana’s international airport was not immediately clear. The travel hub connects more than 20 million Yemenis who live in Houthi-controlled territory to the rest of the world. .
