Clinton thanked Minister Ahmet Davutoğlu for condemning the acts of violence. Clinton has since also requested additional security for diplomatic representatives abroad.

Meanwhile, the United States' administration has requested the video-sharing website YouTube to reassess whether the controversial trailer violates the website's principles.

YouTube restricts sharing footage that includes sexual imagery, promotes drug use, contains violent or hateful statements or is any way related to religious or ethnic-based attacks directed towards certain groups.

At present, YouTube has only restricted the trailer in Egypt and Libya, where it ignited a violent backlash against U.S. missions.
