More gunfire has been heard in the Yemeni capital, Sanaa. Thosuands are said to have fled the city after President Ali Abdullah Saleh was wounded in an attack on his compound. For some, the country is entering a new phase in its ongoing unrest and is edging closer to full-blown civil war.
Seven police officers died when the presidential palace was shelled. State television showed pictures of the aftermath of the attack.
It is the first time Saleh has been directly attacked since the unrest broke out. Officials have denied reports that he has been flown to Saudi Arabia for treatment.
Presidential forces retaliated by shelling the homes of the leaders of a powerful tribal federation they suspected of being behind the attack. The Hashed tribe, led by Sadeq al-Ahmar, has denied the suggestion.
