When the Iranian scientist Professsor Massoud Ali Muhammadi was killed by a remote control bomb on a motorcycle in Teheran last week, President Mahmoud Ahmadinejad accused Israel, saying that it was carried out in the signature “Zionist style” – Interior Minister Mostafa Muhammed Najjar vowed revenge.
So last week’s failed attempt on the lives of Israeli diplomats in Jordan, by a roadside bombing, left very few questions asked, as to who the responsible party may have been. A source said:

“We can see Iran’s fingerprints on the roadside bombing…the investigation is continuing in various directions.”

The explosives may have been smuggled into the Jordanian kingdom by Iranian diplomats, and the attack itself was carried out by local al-Qaida supporters, who received explosives and money from Iran.
The sources in Amman pointed out that the attack on the Israeli diplomatic convoy was carried out in a similar fashion to the assault on the Iranian professor.
Israel has been on high alert in recent weeks ahead of the second anniversary of the assassination of Hezbollah terrorist Imad Mughniyeh in Damascus.

A number of attempts by Hezbollah to avenge Mughniyeh’s February 2008 killing have been thwarted, including a plot to bomb Israel’s embassy in Baku, Azerbaijan, last year. The IDF is concerned that Hezbollah will make an effort to strike an Israeli target ahead of the anniversary.
Security officials are also considering the possibility that the attack may have been carried out by an undisclosed Palestinian terrorist group.
Last year three Hamas activists were sentenced in Jordan to five years in prison for conducting surveillance of the Israeli Embassy in Amman.
