SANAA, Yemen — Two Yemeni presidential advisers say the Shiite rebels who are on a power grab campaign in the capital, Sanaa, are holding the president “captive” at his home, a day after seizing the presidential palace.

The advisers say President Abed Rabbo Mansour Hadi “cannot leave his house” after the Houthi rebels removed his guards and deployed their own fighters at the premises on Wednesday.

One of the advisers says the situation in Yemen has reached the “point of no return,” that the military is in shambles while the country’s security apparatus has been “crippled” after the Houthis’ blitz.

The two advisers spoke on condition of anonymity because they are not authorized to talk to media.
