Dozens of protesters were wounded on Sunday in clashes with government supporters in Yemen's western province of al-Hodayda during their march against the 33rd anniversary of President
Ali Abdullah Saleh's rule, witnesses said, Xinhua reported.
The clashes erupted after thousands of protesters staged a march dubbed a "day of rage" against Saleh's 33rd anniversary in power. Government supporters and policemen in plainclothes wielding batons and knives injured dozens of protesters, who were rushed to hospitals, some of them were in critical condition, the witnesses said.
The protesters hailed the formation of the transitional ruling council, which was announced on Saturday in Sanaa, and shouted slogans against the rule of Saleh, requiring him and his relatives to step down.
Marches against Saleh's 33rd anniversary were also held in other major provinces, including Taiz, Ibb, Dhamar and Saada.
Meanwhile, government supporters staged rallies to celebrate Saleh's 33rd anniversary rise to power in the capital of Sanaa.
The president, who has been treated in Saudi Arabia for bomb injures since early June, has faced six-month-long protests across the country, demanding an end to his 33-year rule.
The Yemeni government officials said Saleh will stay in Saudi Arabia until he gets doctors' permission, expecting him to come back to Sanaa within next few days.
