“Armed robbers ambushed a Saudi prince’s diplomatic convoy on its way to an airport commonly used for private jets, raiding a Mercedes for valuables then torching and abandoning the vehicle, police and prosecutors said Monday. Handguns were flashed but no shots were fired in the Sunday night attack by five to eight assailants, the Paris prosecutor’s office said. No injuries or arrests were reported.
