A senior Iranian military official on Sunday, June 15, warned of a "devastating response" to Israel attacks on the Islamic Republic, adding that Israel would not be habitable as a result.

"The scale of the devastating response by Iran's brave fighters will certainly encompass all parts of the occupied territories (Israel)," said Colonel Reza Sayyad, a spokesman for the armed forces.

"Leave the occupied territories because they will certainly no longer be habitable in the future," and shelters will "not guarantee security", he added in an address broadcast on state television.

Iran won't "negotiate while under attack'

Mediators Qatar and Oman were also told by Iran that Tehran "will not negotiate while under attack", an official briefed on the talks said Sunday, amid an massive exchange of strikes between Israel and the Islamic republic.

"The Iranians informed Qatari and Omani mediators that they will only pursue serious negotiations once Iran has completed its response to the Israeli pre-emptive strikes, while also making it clear that it will not negotiate while under attack," the source said on condition of anonymity because of the sensitivity of talks.

French President Emmanuel Macron on Sunday dismissed the suggestion that Russian President Vladimir Putin could mediate in the escalating conflict between Israel and Iran, citing Moscow's invasion of Ukraine.

"I do not think that Russia, which is today engaged in a high-intensity conflict and has decided not to respect the United Nations charter for several years now, could be in any way a mediator." Macron told reporters on a trip to Greenland. US President Donald Trump said earlier that he was "open" to the possibility after discussing it with Putin.
