The billboards, which depicted the Turkish president as an Ottoman sultan, were reportedly placed in the square by Egypt’s Al-Ghad television news channel.
"The channel’s Cairo bureau hung the billboards, which showed Erdogan sitting on a throne like a [Muslim] caliph," a source from Al-Ghad, who spoke anonymously, told Anadolu Agency.
"A defamation campaign [against Erdogan] has also been launched on Facebook," he added.
The same source went on to note that the Egyptian authorities had removed all the billboards by late Monday evening.
The Al-Ghad television channel is owned -- at least in part -- by controversial Palestinian politician Mohamed Dahlan and is partially financed by the United Arab Emirates.
Currently based in United Arab Emirates, Dahlan was sacked from the Palestinian Fatah movement in 2011 due to allegations of corruption. Hamas, for its part, blames Dahlan for the political turmoil that convulsed the Gaza Strip in 2006 and 2007.
