Yemen's President Abdrabuh Mansur Hadi has arrived in the southern port city of Aden following nearly six months of exile in Saudi Arabia, airport officials say.
Mr Hadi's return comes after he fled Yemen by sea in March as Shiite Houthi rebels and their allies moved on his last refuge in the south.
Hours later, a Saudi-led coalition began launching air strikes aimed at pushing back the Houthis.
The Houthis captured the country's capital, Sanaa, last September and it remains in their control.
Yemen's Cabinet arrived in Aden last week after months of self-imposed exile. Pro-government troops routed the rebels in Aden earlier this summer and have since made a push north.
