The Foreign Ministry also said that a bomber targeted diplomats at Israel's embassy in Georgia earlier today, but the device was diffused by a Georgian embassy staffer before any damage was done.
Avigdor Lieberman, Israel's Foreign Minister, said: "Without going into details, we are able to identify precisely who is responsible for the attack."
Israeli diplomatic staff around the world were already on high alert this week, as Sunday marked four years since the death of Hizbollah's terrorist mastermind, Imad Moughniyeh.
Hizbollah has vowed to avenge his death.
