The wives of the British and German ambassadors to the United Nations have written an open letter to the wife of Syrian dictator Bashar al Assad, asking her to call for peace in her country.

In the unusual move, Sheila Lyall Grant, wife of British ambassador Sir Mark Lyall Grant, and Huberta Voss Wittig, wife of German ambassador Peter Wittig, made the letter into a short video.

The video has been posted on YouTube, urging women all over the world to sign a change.org petition demanding Asma al Assad "stand up for peace ... for the sake of your people".

"We are asking Asma Assad to take a risk ... and to say openly, stop the bloodshed, stop it right now," Lyall Grant and Vos Wittig say.
