When will it end? Protests mounted to new heights in Syria on Friday, as President Bashar al-Assad’s security forces killed at least 12 people demonstrating across the country. Hundreds of thousands of people came out to participate in what were said to be the biggest demonstrations yet against Assad’s rule. Five people were killed in Damascus alone, where police fired ammunition and tear gas to disperse crowds. Four more were killed near the Jordanian border, according to witnesses and activists, and three were shot dead in a northern city. Other than the thousands who have fled to seek refuge in Turkey, Syrian protesters have showed no sign of relenting despite the violent government crackdown.
