After being rejected by TfL it approached billboard companies across Britain but found that three draft adverts were turned down.
ZF director Alan Aziz said: “We are very disappointed that these adverts were rejected, especially given the prominence of DEC’s Gaza appeal adverts which appeared on the underground and buses, adverts which inadvertently supported the notion that Israel was waging a war on innocent children rather than targeting a terrorist infrastructure.”
A TfL spokesperson said: “The adverts submitted for display on our network by the Zionist Federation were not approved by our advertising contractor, Exterion Media.
"Exterion rejected the advert as it contravened our advertising policy which states that adverts will not be approved if they relate to a political cause.”
