Reports quoting Yemeni doctors say that at least 31 people have been killed and more than one hundred injured in clashes during anti-government demonstration in the Yemeni capital Saana. Reports say that incident occurred when pro-government gunmen opened fire at an anti-government protest after Friday prayers. There is no official confirmation to the reports. The doctors, who gave the toll figure, work at a makeshift hospital at the protesters' encampment near Sanaa University. Yemen is facing continuous demonstrations against President Saleh who is in power for more than 32 years.
