Planned in Tehran?

Apropos of previous discussion of the foreign connections of Palestinian terror groups, Israel is now claiming that Iran funded Thursday's Tel Aviv bombing, and has shared intelligence on the matter with foreign governments, including Egypt. If this is accurate, then it shows that just because evidence suggests Hizbullah may have lost influence in the Occupied Territories, Iran may not have, and planning may be going through Damascus instead of Lebanon. Syria might have an interest in the matter as well, if they think it will give them a bargaining chip in future negotiations of the Golan Heights and Sea of Galilee access.
