Transport for London decide to remove bus adverts for an event organised by the extremist Islamic Human Rights Commission:

The adverts were promoting a rally in which people call for the destruction of Israel and show support for terrorists. Further, TfL’s promise to undertake a thorough policy review to prevent similar adverts being placed again is also positive.
