EDIT CONTAINS 4:3 MATERIAL<br/> Amateur video from a social media website shows what it claims is the latest public uprising against the government in Syria.<br/> The video cannot be independently verified by Reuters, but seems to show a protest against President Bashar al-Assad. Demonstrators can be heard calling for his execution.<br/> Another portion of the video purports to show images from the city of Homs-- gunfire can be heard as plumes of smoke rise from the horizon.<br/> Other images show a tank that's gone up in flames after an alleged attack by the Free Syrian Army-- a breakaway military unit.<br/> The United Nations has condemned Syria for quote gross and systematic unquote violations that include executions and the imprisonment of some 14,000 people.<br/> Human rights activists say the death toll from the months-long uprising is close to 4,600.<br/> Julie Noce, Reuters
