The Iranian government is rather upset at actions of the Israel Mossad which over the past few years has been killing leading scientists in their nation. So, the Iranian secret service decided to do a little killing of their own. They asked one of their bumbling agents to blow up a car containing an Israel diplomat, and while a bomb was attached and blew up, it never killed anyone. Oh, the diplomat was not in the car.
In Bangkok, an Iranian agent was preparing a bomb for some member of the Israel Embassy when the darn thing blew up and took off one of his legs. Perhaps, the best policy for Mossad is to supply Iranian agents with explosives, who knows, maybe they will blow up some Iranian scientists!
