Ali Abdullah Saleh, the Yemeni president, has called for a truce and new negotiations after his return to Sanaa after three months, as protests by opposition groups continued across the capital.

"The president calls on all political and military parties to achieve a truce and a ceasefire," said a presidency official.

For Saleh, "there is no alternative to dialogue and negotiations to end the bloodshed and resolve the crisis", the official added.

Saleh had been recovering in Saudi Arabia since suffering injuries in a bomb blast at his presidential palace in the capital, Sanaa, on June 3.
