New York ? Cindy Sheehan, who drew international attention by camping outside President Bush’s ranch to protest the Iraq war, was arrested Monday along with three other women during a demonstration demanding the withdrawal of U.S. troops from Iraq.

The march to the U.S. Mission to the United Nations by about a dozen U.S. and Iraqi anti-war activists followed a news conference at U.N. headquarters, where Iraqi women described daily killings and ambulance bombings as part of the escalating violence that keeps women in their homes.

Women Say No to War, which helped organize the news conference and march, said Sheehan and three other women were arrested while trying to deliver a petition to the U.S. Mission to the United Nations with more than 60,000 signatures urging the “withdrawal of all troops and all foreign fighters from Iraq.” Police said they were arrested for criminal trespassing and resisting arrest.

Richard Grenell, the spokesman for the U.S. Mission, said in response to Sheehan’s arrest: “We invited her in to discuss her concerns with a U.S. Mission employee. She chose not to come in but to lay down in front of the building and block the entrance. It was clearly designed to be a media stunt, not aimed at rational discussion,” Grenell said.

At the news conference Entessa Mohammed, a Baghdad pharmacist, became tearful when recalling the deaths and injuries she said she has witnessed daily. She estimated that 1,600 Iraqis are killed in Baghdad every month, with a greater number injured. “Thanks for the liberation from Saddam” Hussein, she said, addressing the Bush administration, “now please go out.”
