New clashes reported in Iran

TEHRAN, Iran (CNN) - Security forces wielding clubs and firing weapons beat back demonstrators who flocked to a Tehran square Wednesday to continue protests, with one witness saying security forces beat people like "animals."

At least two trusted sources described wild and violent conditions at a part of Tehran where protesters had planned to demonstrate.

"They were waiting for us," the source said. "They all have guns and riot uniforms. It was like a mouse trap."

"I see many people with broken arms, legs, heads - blood everywhere - pepper gas like war," the source said.

Around "500 thugs" with clubs came out of a mosque and attacked people in the square, another source said.

The security forces were ""beating women madly" and "killing people like hell," the source said.

"They beat up a woman so bad she was all bloody," the source said in a description that underscores the growing and central role of women in the uprising.
