Iran plans to place British embassy personnel on trial.

Once again, Iran flouts international norms. The embassy of all countries is considered property of that country, not the country where the embassy is physically located. The taking of the U.S. embassy staff as hostages in 1979 was an act of war, much like an actual invasion. Embassy staff is considered off limits, as are the diplomats stationed there. Even when diplomatic ties are broken, or a war breaks out, embassy staff is escorted out of the country. Without this protection, many people would not become diplomats in the first place and communication between governments would be compromised. Iran once again demonstrates that they are outside of international rules and norms. The leadership of Iran is expert in Islamic law. I guess that Islam allows for such things. After all, Islamic law does not recognize any other legal system or rules.
