Supporters of Yemen's former President Ali Abdullah Saleh perform the traditional Baraa dance during a rally in his support in Sanaa November 7, 2014. The United States on Thursday denied delivering any threats to Ali Abdullah Saleh over what Washington suspects is his role in destabilising Yemen. An official source at the GPC party said on Wednesday that the U.S. ambassador to Yemen had delivered a message through a mediator for Saleh to leave the country by 5 o'clock (1400 GMT) on Friday or face international sanctions.
