Here's an update from a spokesman at the UK foreign office:
Senior officials have spoken to the Iranian charge in London to urge the Iranian authorities to act with utmost urgency to ensure the situation is brought under control and to protect our diplomatic compound, as they are obliged to do under international lawhttp://www.guardian.co.uk/world/blog/2011/nov/29/iran-protesters-attack-uk-embassy-tehran-live
International law only applies to non-white, non-christians? The invasion of Iraq, torture, extreme rendition and cross border attacks that kill Pakistan soldiers are all violations of International law that have led to the death of hundreds of thousands of innocents in the Iraq invasion alone. Where was the outrage from UK foreign officials then? But when twenty non-white, non-christian college students storm an embassy, the international law card is played.
The death rattle of the world's leading democracies grows louder.
