Yemeni security forces fired tear gas and live bullets on Saturday into a funeral procession for people killed in demonstrations earlier this month, injuring 20 people, witnesses said.
The clashes happened in the southern province of Dalea, where two protestors were shot dead on March 11 as security forces broke up a demonstration.
North and South Yemen united in 1990 but many people in the south, home to most Yemeni oil facilities, complain that northerners have used unification to grab resources and discriminate against them.
Last week Yemen's President Ali Abdullah Saleh declared an end to a long-running war with northern Shi'ite fighetrs that drew in Saudi forces last year.
