Yemen's Houthis are expanding targets to include US ships

The Houthi movement in Yemen has announced that it will be expanding its targets to include US ships after the US and UK launched a series of air strikes on Yemeni land positions last week.

Nasruldeen Amer, a Houthi spokesperson, told Al Jazeera on Monday that Washington was "on the verge of losing its maritime security".

On Monday, US-based operator Eagle Bulk Shipping said one of its vessels was hit by an "unidentified projectile" while sailing 100 miles off the Gulf of Aden.
