Two employees of the British Consulate General in Jerusalem have been charged with weapons trafficking in connection to an alleged Hamas plot to fire a missile into the capital's main soccer stadium, Reuters reported.

I guess we have here a diplomatic crisis that will be taken very seriously by Israel. Not as simple as the British passports joke. Terrorism involved, there. Innocent civilian lives targeted.
I'm afraid the British Consul will have to make a clear apology and fire his personnel screening staff, at least. At best, resign after Cameron apologises.
