SANAA, Yemen - Yemen's defiant president addressed his troubled nation on Sunday for the first time since returning to the country after an assassination attempt, making no promise to immediately step down but saying he is committed to a deal to end months of spiraling violence.

Ali Abdullah Saleh appeared in improved health after nearly four months of treatment in neighboring Saudi Arabia for severe burns and other injuries he suffered in a June 3 attack on his compound in Yemen's capital, Sanaa. Saleh abruptly returned on Friday, and a week of renewed clashes with his opponents intensified, littering the streets of the capital with bodies.

"The crisis is big. You who are chasing power, let's all go to the ballot boxes," Saleh said, speaking to his opponents and suggesting elections rather than agreeing to step down.
