WONG:

Cambodian police barred Hollywood actress Mia Farrow and other activists from laying flowers at a "Killing Fields" museum on Sunday. The act was intended as part of a campaign to end atrocities in Sudan's Darfur region.

STORY:

Some 100 baton-wielding and plain-clothed police blocked Farrow from entering the museum, which was once the main torture center for Pol Pot's regime.

Farrow and friends had originally Wanted to light a symbolic Olympic torch in the compound. They were unable to hold a public ceremony, but still tried to visit the museum. But police blocked their path to the entrance.

Farrow spoke to press about her campaign at a nearby news conference. She has held similar events in Chad, Rwanda, Armenia, Germany and Bosnia.
