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.”

Israel's operation against Iran's nuclear program, military leadership and arsenal of missiles is nowhere near over, with Israel having planned out 14 days of operations, a senior Israeli official said.

Hossein Salami, along with some of the country's top nuclear scientists, were killed in the strike. The United States has denied any role in the strikes, but U.S. Secretary of State Marco Rubio said the Trump administration is in close contact with Israel and its allies.

The strike comes after President Donald Trump said the U.S. was "fairly close" to reaching a nuclear deal with Iran.

Sweden and the Netherlands are pressing the European Union to sanction members of the Israeli cabinet over the war in Gaza, joining several other nations in the region whose stance on Israel has hardened in recent weeks.

President Donald Trump warned Thursday of the possibility of “massive conflict” in the Middle East that could take place “soon.”

Precision weapons were also smuggles into central Iran and strategically positioned near surface-to-air missile systems, the official said, adding that Israel also deployed strike systems on vehicles. Israeli media reported that these systems ‘took out’ Iran’s air defences and gave Israeli planes ‘air supremacy’.

World powers respond to rising Middle East tensions as Israel strikes Iranian sites. The U.S. insists it was not involved in strikes, and the much of the globe urges restraint.
