RIYADH (Reuters) - Yemeni President Ali Abdullah Saleh signed a deal on Wednesday under which he stepped down from 33 years in power and 10 months of protests against his rule that have brought the country to the edge of civil war.

Celebrations erupted in Yemen as Saleh signed the deal which made him the fourth leader to be forced from power following the Arab Spring's 10 months of mass protests. Yemenis voiced joy and exhilaration, dancing in the streets and waving flags.
