Violent activity by the Houthis has consisted mainly of armed rebellion against the Yemeni government, leading to clashes with security forces. Thousands have been killed and displaced as a result of the fighting. The Houthis also briefly fought Saudi forces on the northern border in late 2009, and have battled al-Qaeda in the Arabian Peninsula (AQAP) for several years. In October 2016, the rebels took direct action against the United States by conducting a series of failed missile attacks against the U.S. Navy presence in the region.Ryan Browne and Angela Dewan, “US strikes Yemen after missiles launched on warship,” CNN, October 13, 2016, http://www.cnn.com/2016/10/12/politics/pentagon-us-strikes-hit-radar-sites-in-yemen/.
