HARARE, Zimbabwe — A women's activism group says Zimbabwean police using tear gas and batons charged to disperse Valentine's Day marchers, herding 195 people into a police precinct. Twenty-five were later treated for injuries, including broken teeth.

The Women of Zimbabwe Arise leader Jenni Williams said Friday all but one — accused of indecent exposure — were released without charge.

The group traditionally marks Valentine's Day with marches in Harare and Bulawayo giving out red roses as a symbol of peace and love in the troubled nation.

Williams said protesters marched to government buildings to peacefully voice concerns on flaws in a proposed new constitution over women's rights.

Amnesty International, in a statement, said continuing attacks by police on Zimbabwean human rights defenders cast doubt on the country's ability to hold credible polls.
