At least six people have been killed in clashes between pro-democracy protesters and forces loyal to Yemeni President Ali Abdullah Saleh's regime.
Four people lost their lives during protests in the southern port city of Aden on Saturday, and a student was killed in the southern city of Taiz, a Press TV correspondent reported.
Another student demonstrator was killed near the Sana'a University campus in the capital on the same day. The 16-year-old youth was shot dead while government supporters armed with guns, batons, and rocks were trying to break into the campus.
Yemeni security forces reportedly did not intervene.
There were also a number of incidents on Friday.
According to witnesses, at least three pro-democracy protesters were killed on Friday and dozens of others injured during clashes with security forces in Aden's Khor Maqsar district.
A hand grenade hurled into a crowd of demonstrators in the city of Taiz killed two people and left at least 25 more injured.
And Saleh supporters armed with batons and axes attacked a pro-democracy demonstration and wounded at least four protesters in Sana'a on Friday.
Friday's deadly violence came a day after Yemeni riot police opened fire to disperse thousands of pro-democracy demonstrators in Aden, killing four protesters and injuring 17 others.
In Sana'a, 40 people were injured after Saleh loyalists armed with guns attacked a crowd of protesters on Thursday.
Saturday marked the ninth day of pro-democracy protests in Yemen.
Yemenis, angered by corruption and unemployment in the country and inspired by the revolutions in Egypt and Tunisia, are demanding that Saleh step down after 32 years of autocratic rule.
Last week, Saleh again said that he would not run in the 2013 presidential election and would not hand over power to his son.
