Tens of thousands of demonstrators went on streets of Sana'a demanding political reforms on Thursday morning, Al-Jazeera television channel reported.
The demonstrators are divided into two groups - those who support the incumbent president and opposition supporters.
Yemeni President Ali Abdullah Saleh said on Wednesday that he is not going to look for ways to extend his presidential powers, which expire in 2013. Experts believe that such a decision was taken under the influence of the Egyptian President Hosni Mubarak's statement that he would not run for the upcoming presidential elections.
