Protesters run for cover as Kuwait riot police used stun grenades and tear gas to disperse thousands of angry demonstrators who marched on the central prison where a leading opposition figure is detained, in Kuwait City on October 31, 2012. The protest came hours after the public prosecutor extended the detention of Mussallam al-Barrak for 10 days over remarks deemed critical of the emir, in a crackdown on dissent ahead of snap December 1 elections.
