Yemeni security forces used live fire and tear gas today on protesters demanding an end to the rule of President Ali Abdullah Saleh, wounding at least 84, activists said.
Protesters in the southern city of Taiz said 80 people were wounded there and four were reported wounded in the capital Sanaa. State media made no mention of the incidents.
Government website September 26 said there were marches in many cities in support of Saleh and his offers of political reforms, including an offer not to run for reelection in 2013.
The Arabian Peninsula state, neighbour to oil giant Saudi Arabia, has been hit by weeks of protests trying to shake loose Saleh's 32-year grip on power.
The United States, which has long seen Saleh as a bulwark against an active al-Qa'ida wing based in Yemen, has condemned the bloodshed and backed the right to peaceful protest. But it has also insisted only dialogue can end the political crisis.
September 26 said three militants suspected of links to al-Qa'ida were killed when they tried to attack a military checkpoint today in Marib province. Also today, security forces said they had arrested two suspected al-Qa'ida members.
Both pro- and anti-government factions appeared to be increasingly resorting to violence, but activists said protesters had not used force in the latest demonstrations.
Some 150 people were wounded on Wednesday when security forces tried to break up a rally in the Red Sea city of Hudaida.
