Yemen's ambassador to the United Nations is asking the international community to quickly intervene with ground forces to save the country from Houthi rebels who have been targeted by Saudi-led airstrikes for weeks.

A letter sent Wednesday to the president of the U.N. Security Council and obtained by The Associated Press also calls on human rights organizations to document what Ambassador Khaled Alyemany calls the Houthis' "barbaric violations against a defenseless population."

The call for the use of ground forces comes as the international community instead calls for an immediate ceasefire, or at least humanitarian pauses, to deliver aid to civilians trapped in the fighting.

The fighting has turned into a proxy war between Saudi Arabia and Iran, which backs the Houthis.

Alyemany did not immediately comment.
