Timeline: Yemen war began in 2014 when Houthis seized Sanaa

CAIRO (AP) — Yemen’s Houthi rebels on Wednesday targeted an airport in southwestern Saudi Arabia, causing a civilian plane on the tarmac to catch fire. The attack came just a few days after President Joe Biden announced the U.S. would end its support for the Saudi-led coalition’s war against the Houthi rebels.

Yemen’s war began in September 2014, when the Houthis seized the capital Sanaa. Saudi Arabia, along with the United Arab Emirates and other countries, entered the war alongside Yemen’s internationally recognized government in March 2015. The war has killed some 130,000 people and driven the Arab world’s poorest country to the brink of famine.
