Yemen's President Ali Abdullah Saleh said yesterday that he will not step down or allow the country to become a "failed state", as battles raged and protests, left, continued in the capital for a third day.

The clashes have left at least 41 dead, and sharply increased chances that the uprising could turn into a militia-led revolt.
