A spokesman for embattled Yemeni President Ali Abdullah Saleh says talks with the opposition have made no progress toward a deal on the president's possible resignation.
Ahmed al-Sufi says Saleh's vice president and political adviser met Saturday with the U.S. ambassador and tribal and military leaders who have defected to the opposition.
Al-Sufi said the ruling party wanted to discuss a transition, but that the opposition demanded Saleh's immediate resignation. He called the demand unacceptable.
Saleh has responded to weeks of demonstrations calling for his ouster with violence and promises to leave power only in an "honorable" way. The opposition says he's stalling.
The U.S. Embassy declined to comment.
