( CNN ) -- Eleven people were killed Tuesday during clashes with Yemeni security forces after anti-government protests again filled the streets of the country 's capital , according to a hospital official . Crowds marched through downtown Sanaa , where government forces allegedly gunned down protesters -- the latest in a series of confrontations between those loyal to embattled President Ali Abdullah Saleh , demonstrators and rival factions . Hundreds of security forces attempted to restrict the protesters ' movements , and tear-gas canisters could be seen flying toward the crowd , said hospital director Mohammed Qubati . Others carrying sticks and knives also advanced toward the crowds , Qubati added . CNN has not independently confirmed the details of casualties , and the government has not yet responded to requests for comment . The violence comes one day after thousands of women demonstrated in front of Yemen 's Foreign Ministry in Sanaa , demanding U.N. intervention in the ongoing unrest in the Persian Gulf nation . The women called for sanctions against Saleh and asked that the International Criminal Court try him . Saleh said Sunday that `` strong documentation of the cooperation '' between al Qaeda and the Muslim Brotherhood indicate a military coup that is destabilizing the country . He described the opposition as `` insane people , who ca n't sleep and only want to take power . ''
