"They say they will not be blowing up ships any more," the US president said of the Yemeni militants, claiming to have bombed them into submission. Well, the Houthis are back - and apparently stronger than ever.

The port of Eilat, already diminished, could shut down entirely without government assistance in what would be a win for the Houthis, officials warn.
