Tehran has asked Qatar, Saudi Arabia and Oman to press U.S. President Donald Trump to use his influence on Israel to agree to an immediate ceasefire with Iran in return for Tehran's flexibility in nuclear negotiations,

President Trump arrived in Canada for the G7 summit, where the Israel-Iran conflict will be a key issue for world leaders. NBC News' Gabe Gutierrez reports on the possible pressure Trump could face to de-escalate tensions between the countries.

"The full strength and might of the U.S. Armed Forces will come down on you at levels never seen before," Trump warned.

Trump warns Iran not to retaliate against U.S. targets in the Middle East while also predicting Israel and Iran would 'soon' make a deal to end their escalating conflict.

Israel’s attack on Iran was long in the making – the result of years of meticulous planning by Israel and days of high-stakes talks between Tel Aviv and Washington, officials told CNN.

President Trump is trapped between the “America First” isolationists and others in his party who are cheering on Israel’s strikes against Iran.

In response to Israel’s attack, Iran fired back with more than 100 drones. NBC News’ Chief International Correspondent Keir Simmons reports more. Former NATO Supreme Allied Commander retired Gen. Wesley Clark and Senior Fellow at the Carnegie Endowment for International Peace Aaron David Miller join Ana Cabrera to examine the possibility of further attacks.

“They should now come to the table to make a deal before it’s too late. It will be too late for them. You know the people I was dealing with are dead, the hardliners,” he added. The strikes killed the head of Iran's Revolutionary Guard Corps, and the country's top two military officials, in addition to several nuclear scientists.
