Houthi rebels declared a new government in Yemen in February 2015 after UN-brokered talks to try to resolve a political crisis broke down.
The rebels said a five-member presidential council would replace the president during a period of transition.
They said parliament had been dissolved and replaced by a transitional national council.
Both President Mansour Abdrabbuh Hadi and his government resigned in January 2015 after the Houthis tightened their grip on Sanaa.
Yemen has been in political limbo since President Hadi and the government resigned after the Houthis seized the presidential palace in a struggle to tighten control.
