Houthi rebels in Yemen are holding multiple Americans prisoner

The rebel group that has seized power in Yemen has taken at least four U.S. citizens prisoner, according to U.S. officials who said that efforts to secure the Americans’ release have faltered. One of the prisoners had been cleared for release in recent days only to have that decision reversed by members of the Houthi rebellion that toppled the U.S.-backed government earlier this year and now controls most levers of power in Yemen.
