Tens of thousands of protesters attended a rally on Monday in the southern Yemeni city of Taiz, some 260km south the capital Sana'a.
The protesters renewed their calls for discharging the province's security chief Abdullah Qairan , Republican Guards commander Murad al-Awbali, Taiz governer Khaled al-Sufi, who were heavily involved in attempting to quell the peaceful protesters, killing hundreds and injuring thousands.
The demonstrators chanted slogans condemning the parliament for passing the controversial immunity law that protects Yemeni outgoing President Ali Abdullah Saleh and his top aides from prosecution, and demanding the trial of everyone involved in the clampdown on the protesters.
Taiz , the scientific hub and spark of Yemeni revolution, has witnessed popular protests calling for an end for the autocratic rule over the last year.
Saleh has signed a deal under which he transferred his executive powers to VP Abdu Rabu Mansour Hadi, the sole candidate for the upcoming Presidential elections set to be held on February 21, in exchange for immunity from prosecution.
Saleh has left Yemen for US to receive further medical treatment for wounds sustained in an assassination attempt early in June.
Even though high-profile figures form saleh's General People Congress parts insist that he would be back, many political analysts believe that his televised appearance on Sunday was his last and that he left the country for good.
