A Chinese women's rights group says five feminist activists remain in police custody after authorities detained at least eight activists across the country in the run-up to International Women's Day.

Women Center board member Lu Jun said Monday that the detained activists include Li Tingting, Wei Tingting, Wang Man and Wu Rongrong, the founder and executive director of the Hangzhou-based rights group. Lu said their lawyers have not been able to reach them since their detention Friday.

Lu said the women had planned to observe International Women's Day by putting up leaflets about sexual harassment in Beijing, Hangzhou and Guangzhou. He said the activists have previously observed the day without interference.

Police in Beijing and Guangzhou did not respond to requests seeking comment.
