ROUGH CUT (NO REPORTER NARRATION)
Eleven Cambodian protesters are detained by police and security guards in Phnom Penh.
The activists had joined a march, and were delivering a petition to the French embassy, to seek help in securing the release of their fellow activists.
Guards at the city hall stopped the mostly female activists, and police took them for questioning. A city hall official said the protest was illegal.
Police have banned gatherings of more than 10 people, after a violent crackdown against demonstrations by garment factory workers earlier this month.
At least four people were killed in the protest, which gathered together about 350,000 people and posed one of the most serious challenges to Prime Minister Hun Sen's 30-year rule.
