Witnesses and medical staff said at least 30 people were also injured in the fighting between Saleh`s Republican Guards and opposition tribesmen in Yemen`s third largest city, a hotbed of anti-Saleh protests some 200 km (120 miles) south of Sanaa.
An eight-year-old girl was killed and her mother was critically wounded in further shelling on al-Hasab neighbourhood in the western part of the city, hospital officials said, raising to three the number of children killed in the clashes.
Three women also died in the shelling of the al-Rawda and Zaid al-Moshki districts as well as Freedom Square, where demonstrators demanding an end to Saleh`s 33-year rule gather for Muslim noon prayers every Friday.
Saleh`s forces later shelled the al-Rawda Hospital, where victims of earlier fighting had been taken, killing one patient and wounding five people. They said patients had to be rushed for safety into the basement after the shells damaged the third and fourth floor.
"The hospital was hit by nine shells, and the third and fourth floors have been damaged," one witness in Taiz told Reuters.
Saudi Arabia, the world`s largest oil exporter which shares a long and porous border with Yemen, is worried violence in Yemen may strengthen al Qaeda militants based there who have launched attacks in the past on U.S. and Saudi targets.
In the capital Sanaa, tens of thousands of anti-Saleh protesters attended prayers on a main road. Some demanded the president be tried for what they called his crimes against the Yemeni people.
Separate prayers were held by thousands of Saleh supporters in the capital. There were no reports of violence in Sanaa.
The fighting in Taiz started on Thursday after gunmen shot and critically wounded a soldier stationed at a government building. This was followed by the killing of a pro-Saleh tribal leader and the wounding of one of his bodyguards.
U.N. envoy Jamal Benomar arrived in Sanaa on Thursday to encourage "an inclusive transition process that meets the needs and aspirations of all Yemenis", a spokesman said.
Martin Nesirky, spokesman for U.N. Secretary-General Ban Ki-moon, said Benomar would report back to Ban, who is to inform the U.N. Security Council about the implementation of a resolution adopted last month that called on Saleh to accept a Gulf-brokered plan under which he would step down. (*)
