Actress Anne Hathaway attended a protest march here to call for the release of the kidnapped Nigerian schoolgirls.

The Oscar winner and her husband Adam Schulman became the latest celebrities to back the cause, and marched the streets here on Thursday in a Bring Back Our Girls rally, reports contactmusic.com.

The teenagers were kidnapped from a school in northern Nigeria last month during a night raid by members of the Boko Haram extremist group, who want to keep them the girls away from western education.

To demand urgent action over the scandal, the actress used a megaphone to lead the crowd in chants to support the cause.

Documentary filmmaker Ramaa Mosley, who attended the rally, said: "She (Anne Hathaway) came and surprised us and her voice was louder than everybody else. They were yelling at all the cars (passing by)!"

Hathaway is just one of the many stars to show support for the Bring Back Our Girls campaign, which was first launched on Twitter.
