It wouldn't be a wedding without an argument over the guest list. Human rights groups are criticizing the decision to invite Syria's ambassador Sami Khiyami to Prince William and Kate Middleton's nuptials while his government wages a violent crackdown against opponents. More than 450 people have been killed in the uprising against President Bashar Assad's authoritarian regime. The government said Thursday that ambassadors from all countries with which Britain has "normal diplomatic relations" have been invited some 185 in all. (AP Photo/ Fiona Hanson/Pool)
