"I can't tell which is louder, the mortar fire in Sana'a right now or the media's beating of the civil war drum."
He cautions that, so far, this fighting has been limited to a single group of tribesmen. The violence is intense, and dangerous, but it is not a war between thousands of protesters and the government. He also raises the idea that President Saleh may have sparked this conflict in an attempt to paint the protesters as terrorists.

NATO said that a number of the strikes hit a vehicle storage facility adjacent to the Bab al-Aziziya compound. It was not clear if the facility was the only target.
0500 GMT: We begin again in Sanaa, the capital of Yemen. A day after the bizarre collapse of the deal for a transition of power, with armed supporters of President Saleh trapping envoys in the Embassy of the UAE, there was a twist in the military situation.

At least 14 were killed and 36 injured in the clashes. A source in the ministry said gunmen killed all the guards.
The tribesmen also attacked the headquarters of the national air carrier, Yemenia Airways, and a number of other government buildings, setting some of them on fire.
Earlier in the day, the battle had begun near the house of Sheikh Sadeq al-Ahmar, the leader of the powerful Hashid tribe, killing two of his supporters and injuring 25. All-Ahmar has turned against President Saleh.
