Speculation about Saleh's health and the likelihood of his return to Yemen has been rife since he was hurt in a bomb blast on June 3 in a mosque in his presidential palace. He flew to Saudi Arabia for treatment, leaving behind a country on the verge of civil war.

The president has not been seen in public since the explosion, which killed several people and wounded the prime minister, two deputy prime ministers and the speakers of both parliamentary chambers. It is not clear what role if any Saleh, under pressure to step down, sees for himself in ruling Yemen.

"He will appear within the next 48 hours despite our fear that the burns on his features and on different parts of his body will be an obstacle given that his appearance will not be as the media expects it," said Ahmed al-Sufi, the President's media secretary.

Yemen has been rocked by months of protests against Saleh's three decades of rule. Before that he was grappling with a rebellion in the north, separatist violence in the south and a resurgent wing of al Qaeda.

Sufi said Saleh was in good health and continued to direct Yemeni affairs from abroad. Saleh's deputy Abd-Rabbu Mansour Hadi has been at the helm while the president recovers.

A source close to the president said Saleh's condition was good enough to allow him to travel to Yemen soon.

"The bomb in the mosque was in close proximity to the president when it went off. He was really lucky to get out," the source, who was with Saleh during the attack, said.

Saleh is suffering from burns but they cover less than 40 percent of his body, the source said, addressing reports in recent weeks about the extent of his injuries.

Yemeni officials previously accused an opposition tribal coalition of shelling the palace, which it denied.
