Very unlikely the Iranians were behind such a clumsy attack.
While they certainly have motive and opportunity, they wouldn’t have botched the attacks so badly and likely would have had many more targets.
Update:
Those attacked:
Tal Yehoshua (40), wife of Israeli Defence Attache
Indian driver Manoj Sharma (42)and in the following car: Arun Sharma (61) and Manjit Singh (75)
The Tblisi bomb had been duct taped to the bottom of the car.
The Delhi bomb was attached magnetically to the rear hatch.
Both bombs had no shrapnel and were essentially fire bombs made of potassium chlorate with sulphur, with sulphuric acid as the trigger.
Seems too simple and ineffective to be an Iranian or Talib or TET origin.
It’s a mistake to believe just because the Mullahs are shrewd, malicious SOBs, they therefore can find talented contractors for their terror work in both India and Georgia, and coordinate the timing as well. Also, they were trying to imitate the tactic used against one of their scientists, the magnetic bomb on the car attached by a passing motorcyclist. It’s a great trick, but not every operative can ride a bike, and not every biker is an operative. It’s not like delivering pizza.
