On Thursday, it was revealed Syria's ambassador to London, Dr. Sami Khiami, had been uninvited amid mounting international concern at political unrest in the nation.

"In the light of this week's attacks against civilians by the Syrian security forces, which we have condemned, the Foreign Secretary has decided that the presence of the Syrian Ambassador at the Royal Wedding would be unacceptable and that he should not attend," the Foreign Office said in a statement.

Networks and cablers are going all out in their coverage of the nuptials.

Entertainment Tonight executive producer Linda Bell Blue tells The Hollywood Reporter there are 70 staffers overseas.
