SANA, Yemen — A Saudi-led military coalition carried out at least seven airstrikes on the international airport here on Tuesday, possibly crippling the airport in order to prevent an Iranian airplane from landing, according to Saudi and Yemeni officials.

The airstrikes hit the main runway, endangering one of Yemen’s last usable airports and a major transit point for global aid shipments. An airport official said the damage had made it impossible to use the runway.

The bombings demonstrated the extent to which Yemen has become trapped in the escalating regional proxy war between Saudi Arabia and Iran. Saudi Arabia began its bombing campaign against the Houthi rebel movement in Yemen last month in large part to counter what Saudi officials saw as the influence of Iran, which has supported the Houthis.

Saudi accusations that the Houthis were acting as an instrument of Iranian power were viewed by many Yemenis and Western diplomats as exaggerated or misplaced. Even so, the war in Yemen has ratcheted up tensions, raising fears of a broader conflict.
