Iran will stop sharing information with the International Atomic Energy Agency about new and special measures to protect its nuclear materials and equipment, Iranian nuclear negotiator Kazem Gharibabadi told Iranian state media,

The two sides were scheduled to meet for a sixth round of negotiations on Sunday. Oman, which was set to host the talks, said on Saturday that this round had been canceled.

Experts suggest the U.S. has a strategic opportunity to leverage Iran's weakened position for a nuclear deal after Israel's targeted strikes on Iranian nuclear and military sites.

A series of loud explosions are heard in central Israel as the military says it carried out intelligence-based strikes in Tehran.

As the attacks escalate, with fatalities and injuries reported on both sides, Israel issued the stark warning to Iran.

Former MSNBC host Chris Matthews criticized former President Obama's Iran nuclear deal following Israel's strike on Iran, saying Trump was fair to call the deal a "joke."

Israel's PM says it struck Iran at the heart of its "weaponization programme", but Iran insists its nuclear facilities were peaceful.
