Yemen’s Houthi movement launched a ballistic missile deep into Saudi Arabia and may have also fired on a U.S. warship, two days after an apparent Saudi-led air strike killed 140 mourners at a funeral attended by powerful tribal leaders.

Saturday’s air strike ripped through a wake attended by some of the country’s top political and security officials, outraging Yemeni society and potentially galvanizing powerful tribes to join the Houthis in opposing a Saudi-backed exiled government.
