By Alexander Cornwell and Parisa Hafezi TEL AVIV/DUBAI (Reuters) -Israel and Iran attacked each other for a fifth straight day on Tuesday, and U.S. President Donald Trump urged Iranians to evacuate Tehran,

Iranian officials have warned that U.S. participation in an attack on its facilities will imperil any chance of the nuclear disarmament deal the president insists he is still interested in pursuing.

Israel and Iran have begun a new round of attacks, as the conflict between the two heavily armed rivals enters its fourth day.

The White House and Israeli Ministry of Foreign Affairs did not immediately respond to The Post’s request for comment.

Only the U.S. military has the 30,000-pound bomb capable of reaching the facility and the bomber that can carry it.

While the U.S. insists it is not involved in strikes on Iran, American officials have confirmed military forces have been helping to intercept Iranian missiles fired at Israel.

"American Forces are maintaining their defensive posture & that has not changed," the chief Pentagon spokesperson said.

What we are seeing now is the rhetoric — and the wisdom — of “America First” become reality in the skies over Tehran.
