Trump's decision came after Israel and Iran have exchanged consistent strikes since June 13. Israel had urged the U.S. to target Iran's nuclear facilities, saying that Tehran was moving close to creating a nuclear weapon. Iran maintains that its nuclear program is for civilian, not military, purposes.

Iran's supreme leader sent his foreign minister to Moscow on Monday to ask President Vladimir Putin for more help from Russia after the biggest U.S. military action against the Islamic Republic since the 1979 revolution over the weekend.
