Protests Continue in Yemen VOA News February 25, 2011 A Yemeni anti-government protester holds up a placard that reads 'This is enough' during an anti-regime demonstration calling on President Ali Abdullah Saleh to leave in the capital Sana'a, February 24, 2011 Photo: AFP A Yemeni anti-government protester holds up a placard that reads 'This is enough' during an anti-regime demonstration calling on President Ali Abdullah Saleh to leave in the capital Sana'a, February 24, 2011 Thousands of people have gathered in the Yemeni capital, Sana'a, for rallies to be held after Friday prayers. Anti-government protesters are clustered in a square near Sana'a University to call for the resignation of President Ali Abdullah Saleh, as they have been doing for days. Pro-government supporters are also expected to rally on Friday in the capital. Thursday, Yemen's state-run media said President Saleh has ordered security forces to prevent any clashes between pro- and anti-government protesters. He also urged both sides to take precautions against those who may try to infiltrate the protests and incite violence. At least 12 people have died in Yemeni demonstrations since the protests began earlier this month. Clashes took place on Tuesday near the university when attackers using guns and other weapons tried to disperse the protesters, who have been camping out at the site for days. At least seven members of parliament submitted their resignations from the ruling party Wednesday to protest the government's violent response to the demonstrations. They said they would form an independent bloc in the legislature. Protests challenging Mr. Saleh's 32-year rule took place in other parts of the country Wednesday. Demonstrators and security force members clashed in the port city of Aden. Also, thousands of chanting anti-government demonstrators marched through the eastern city of al-Mukalla.  Follow our Middle East reports on [1]Twitter and discuss them on our [2]Facebook page.
