Forces loyal to Yemeni dictator Ali Abdullah Saleh shelled the city during the late hours of Saturday.
Tens of thousands of anti-government protesters held a demonstration in Taizz on Sunday, calling for the downfall of the regime.
The protest in Taizz came as on Saturday after Yemeni Vice President Abdrabuh Mansur Hadi announced February 21 as the date of presidential election in the country. This will be the first presidential election in Yemen since 2006.
The Yemeni vice president is expected to form a national unity government ahead of the election.
On Saturday, Yemeni opposition parties nominated Mohammed Basindawa, the head of their coalition and a former member of Saleh’s ruling party, to lead the government after Saleh resigns.
Saleh signed a power transfer deal brokered by the (Persian) Gulf Cooperation Council in the Saudi capital, Riyadh, on Wednesday.
Under the deal, the Yemeni dictator will transfer his powers to his deputy ahead of the February election and receive immunity from prosecution in return. However, Yemeni protesters reject any deal giving immunity to Saleh, whose son and three nephews still hold powerful posts in the security services.
Hundreds of people have been killed and thousands more have been injured in Yemen since the beginning of the uprising against the Saleh regime in late January.
UN Security Council Resolution 2014, which was unanimously passed on October 21, expressed “grave concern” at the situation in Yemen.
