Cambodian police have fired live ammunition at protesting garment workers outside the capital, injuring at least six protesters and killing a bystander.

The human rights group Licadho says hundreds of workers from the SL Garment Processing (Cambodia) Ltd. Factory clashed Tuesday with about 1,000 riot police sent to block a march from the factory to the Phnom Penh residence of Prime Minister Hun Sen.

Am Sam Ath of Licadho says protesters threw rocks at the police, who responded with tear gas, rubber bullets and live ammunition. A bystander was killed after being struck by a bullet while selling rice on the roadside.

Workers from the factory have been protesting for months for better working conditions and pay.

The factory makes clothing for Gap, H&M and other international brands.
