Yemen's Shiite rebels have announced a formal alliance with the country's ousted president and his onetime ruling party by forming a new political council to rule the country.

The rebels, known as Houthis or Ansar Allah, signed a deal on Thursday with the General People's Congress, led by the ousted President Ali Abdullah Saleh, agreeing to form a council of 10 members, five from each party. The two sides will work together to confront the Saudi-led military coalition, which supports the internationally-recognized government months after it fled the country. The Houthis have controlled the capital, Sanaa, since 2014.

The new agreement, which doesn't change much on the ground, is expected to further complicate the difficult U.N. peace talks in Kuwait between the Houthis and the government.
