Two people have been killed and dozens wounded in clashes in Yemen between Islamists and separatists during rallies marking the 2011 uprising that led to the ouster of President Ali Abdullah Saleh. Members of the Islamist Islah party and southerners calling for independence fought in Aden during the protest. Security officials say both sides fired live ammunition at each other, killing a bystander and a 25 year-old separatist. Meanwhile, thousands of people marched peacefully in the capital Sanaa.
