In a letter to the UNSC late on Tuesday, Takht Ravanchi said over the past months, the number and intensity of Israel's "provocative and adventuristic threats" to Iran's nuclear program have consistently grown and reached an alarming level.

The Iranian envoy referred to the latest remarks by Israeli senior military officials of "operational plans against Iran's nuclear program," saying that "such systematic explicit and public threats by the Israeli regime against a founding member of the United Nations constitute flagrant violations of international law."

Takht Ravanchi warned against any possible military act of Israel against Iran and its nuclear program, stressing that Iran reserves the right to self-defense to decisively respond to any threat.
