Demonstrators in Cambodia have begun a third week of protests demanding new elections, their numbers buoyed by thousands of factory workers seeking higher wages.

Sam Rainsy, leader of the opposition Cambodia National Rescue Party, led a march of tens of thousands of people through the capital of Phnom Penh on Sunday in the group's latest and largest daily protest.

Prime Minister Hun Sen won elections in July that extended his 28-year rule, but his opponents accuse him of rigging the vote. The protests expanded this past week when workers from garment factories, a linchpin of the country's economy, joined the anti-government demonstrators, adding their own demand for a higher minimum wage.
