Israel launched a series of airstrikes across Iran early Friday, targeting critical nuclear facilities in Iran.

President Donald Trump has issued a stark warning to Iran, urging the country to accept a nuclear deal to avoid further “planned attacks,” citing that “there has already been great death and destruction, but there is still time to make this slaughter… come to an end.”

Iranian military chiefs and nuclear scientists were among those killed in what Iran's foreign minister calls a "declaration of war".

Stock futures in the U.S. dropped and global oil prices jumped following an Israeli strike targeting Iran's nuclear facilities.

In the wake of a series of strikes by Israel on Iran's nuclear sites, potentially pushing the Middle East to the brink of an all-out conflict, President Donald Trump told ABC News he thought the attacks had been "excellent" and suggested there was "more to come."

UNITED NATIONS (Reuters) -The United Nations Security Council will meet later on Friday over Israel's strikes on Iran, diplomats said, at the request of Tehran.

President Trump made his first public comments since Israel's military began its assault on Iran, urging it to "make a deal, before there is nothing left."

The U.S. did not provide any assistance or have any involvement in the Israeli strike, a U.S. official told ABC News. ABC News' Chief Washington Correspondent Jonathan Karl spoke to President Donald Trump on the phone early Friday morning and asked him about the attack on Iran.
