SANAA (Reuters) - - Talks aimed at ending Yemen's political crisis faltered on Sunday when three of the country's main political parties quit negotiations with the Iranian-backed Shi'ite Houthi group, raising the prospect of growing chaos.

The parties, which are seen as close to President Abd-Rabbu Mansour Hadi, said they walked out of the talks after the Houthis reneged on previous promises.
