From Palestinian Media Watch:

Less than 24 hours after the July 7 terrorist bombings in London, a Palestinian Authority Television sermon called for the extermination of every single Infidel:
“Annihilate the Infidels and the Polytheists! Your [i.e. Allah’s] enemies are the enemies of the religion! Allah, disperse their gathering and break up their unity, and turn on them, the evil adversities. Allah, count them and kill them to the last one, and don’t leave even one.”
[Suleiman Al-Satari, PA TV, July 8, 2005.
