Yemen's Houthi rebels said 240 injured members of the group returned home on Wednesday through two Omani planes after they received treatment abroad, the group's al-Masirah TV reported.

They arrived in Houthi-controlled Sanaa airport, the television said without providing more details.

Yemen's airspace has been controlled by the Saudi-led coalition since its intervention in the Yemeni conflict in March 2015 to support the internationally-recognized government of President Abd-Rabbu Mansour Hadi.

Yemen has been mired in civil war since late 2014, when the Iran-backed Houthi militia seized control of several northern provinces and forced the government of Hadi out of capital Sanaa.

The United Nations is trying to end the conflict that has killed tens of thousands of people and pushed the country to the brink of famine.
