Police officer inspects the damaged windshield of a police bus after clashes between police and rubber farmers in Bangsaphan

A police officer inspects the damaged windshield of a police bus after clashes between police and rubber farmers in Bangsaphan, Prachuap Khiri Khan September 6, 2013. Thailand faced pressure on Friday to end a two-week protest by rubber farmers after violent overnight clashes between riot police and a group of protesters who hurled rocks and bottles filled with an acidic liquid. Police fired tear gas to disperse the group in Prachuap Khiri Khan province on a main road from Bangkok to the southern beach resort region of Phuket. At least 21 policemen were injured, authorities said. Tens of thousands of farmers in the country's main southern rubber-producing region are demanding greater state support after a slowdown in demand from China and concerns over global economic growth sent prices tumbling to multi-year lows in mid-2012.
