Iran is threatening "a severe, extensive and painful response" to the "slightest action" of retaliation by Israel to its previous drone and missile attacks with "weapons that we have not used before" after receiving arsenal from Russia.
Abolfazl Amouei, a spokesperson for the Iranian Parliament's National Security Committee, told a local media outlet that the Islamic Republic "will confront any Israeli aggression and respond to it," the Economic Times reports.
"We are ready to use weapons that we have not used before, Amouei told Al-Mayadeen News. “We have plans for all scenarios, and we call on the Zionists to act rationally.”
Iranian President Ebrahim Raisi had separately warned that it planned a "severe, extensive and painful response" if Israel took even the "slightest action."
“The blind support of some Western countries to the Zionist regime is the cause of tension in the region,” Raisi claimed, according to the Daily Express.
Iran launched an attack Saturday that swarmed Israeli airspace with hundreds of drones and missiles and reportedly resulted in limited damage, but showed deterrence without resulting in an all-out war, experts told NBC News. Iranian armed forces chief of staff Maj. Gen. Mohammad Bagheri shared a public statement confirming the attack "concluded and we are not willing to continue it" hours after the strike took place.
An Israeli official in Prime Minister Netanyahu's office said the country planned to "consult with all its partners but ultimately it's Israel's decision as to what the response will be" via NBC News.
“Israel can’t allow such a large attack over Israel without some kind of response, be it small or large,” the official said. “It’s up to the war cabinet to decide now.”
On Sunday (April 14), NBC News reported that some of U.S. President Joe Biden's top officials feared that Israel's response to Iran's drone and missile attacks could potentially drag the U.S. into a wider war. Biden, who publicly reinforced his administration's "ironclad" commitment to aiding Israel's defense, was reported to have privately expressed concern that Israeli Prime Minister Benjamin Netanyahu was attempting to drag the American military into a much larger conflict, three sources with knowledge of the situation confirmed to NBC News.
Biden told Netanyahu that the U.S. wouldn't participate in offensive operations in Iran and advised Israel not to retaliate against Iran during a phone call Saturday (April 13) night, a senior administration official confirmed to NBC News.
