What You Need to Know About Yemen In 75 Seconds

— -- A turbulent week in Yemen has drawn global attention after a Shiite tribal group known as the Houthis surrounded the presidential palace and occupied several major government buildings in the capital of Sanaa.

Yemen is considered a key ally in the fight against terrorism, and the crisis prompted concern from U.S. officials who monitored closely the situation at the U.S. embassy, where 100 Marines stood guard over dozens of Americans inside.

Wednesday the rebels reached a deal with Yemeni President Abed Rabbo Mansour Hadi to resolve the crisis in the capital in exchange for constitutional changes and political power, but there are widespread doubts that the deal will lead to lasting peace.
