On 3 January at least four people were shot to death and 20 others were injured when police opened fire to break up a protest by garment workers. The workers were demanding their minimum wage be doubled. They had blocked the road with burning tires. Protesters also threw objects at police. By this time most of the workers at Cambodia's 500 factories were on strike. The demand was still for a $160 a month in minimum wage while the government had offered $100. This was the second day of strikes and clashes with police. The opposition party and anti-government protesters have close ties with the labor movement. Unions representing disgruntled garment workers joined the protest with opposition supporters against the government of Prime Minister Hun Sen. They want a re-run of the July election. Sam Rainsy, CNRP leader promised to nearly double wage to $160 if CNRP wins a re-election.
