Yemen Houthi rebels free six foreign hostages

Yemen's Houthi rebels have released six foreign hostages including at least two Americans, two Saudis and a Briton, officials say.

There are no details on their identity. They have been flown from the capital Sanaa to neighbouring Oman.

Shia Houthi rebels have seized much of Yemen, including Sanaa, since last year. They are fighting government troops aided by a Saudi-led coalition.
