At least 30 police officers in southern Thailand were injured Monday in a new round of clashes with demonstrators protesting what they considered to be an inadequate government offer to help rubber farmers. The protesters clashed with police as they attempted to reclaim a traffic intersection they previously blocked in Cha-uat district in Nakhon Si Thammarat province, said Police Maj-Gen Somchai Uamthanom. Somchai said protesters, mostly teenagers, hurled rocks, bricks and bags of acidic liquid at officers who responded with tear gas. An unknown number of protesters also were hurt. Tension was renewed over the weekend in southern provinces after farmers declined the government’s offer to subsidize rubber prices.
