SANAA, Sept. 21 (Xinhua) -- The Yemeni government and Houthi rebels signed a ceasefire deal Sunday night after days of deadly clashes in the capital Sanaa, a government official told Xinhua.

　　The two sides agreed to cease their fire in Sanaa immediately, nominate a prime minister in a week and decrease fuel prices, the official said anonymously.

　　The deal empowers the Houthi rebels as it allows the group to play an important role in forming a cabinet and determining the future control of the army, the official added.

　　Deadly clashes between the rebels and army supported by Sunni militia broke out on Tuesday in northwestern Sanaa that have left more than 200 people killed, including some 50 civilians.
