Israel has lodged a complaint before the United Nations chief over the alleged terror campaign launched by Iran and its "proxy" Hezbollah against Israeli targets in recent weeks, including in India and Thailand.
"This campaign bears the unmistakable fingerprints of the Iranian regime and the highest echelons of the Hezbollah leadership.
"Their actions constitute a clear threat to security and stability of Lebanon, to the Middle East, and to many countries that have been targeted," Israel's Permanent Representative to the United Nations, Ron Proser, said in a letter to UN Secretary General Ban Ki-moon.
In each of these instances in Thailand, India, Bulgaria, Georgia and Azerbaijan, the letter said, Iran and Hezbollah have "sought to harm innocent civilians and have flagrantly violated the sovereignty of member states."
Noting that an Israeli embassy car was targeted in New Delhi on Monday and Iranian suspects were apprehended over Tuesday's Bangkok blasts, it said these are not isolated incidents.
"Iran has long employed international terrorism as a pillar of its foreign policy, often using Hezbollah as a proxy to stage attacks," the letter said.
The UN Security Council should have condemned the attacks in New Delhi, Tbilisi and Bangkok immediately, it said.
"Israel expects it to issue a clear condemnation... without any further delay or equivocation. The Council must also address this threat by considering active steps against Iran, Hezbollah and their terrorist infrastructure worldwide," the letter said.
