The U.S. military has moved a large number of refueling aircraft to Europe to provide options to President Donald Trump as Middle East tensions erupt into conflict between Iran and Israel, two U.S. officials told Reuters on Monday,

Iran, however, has said that it would hold the U.S.—which has provided Israel with much of its deep arsenal of weaponry—for its backing of Israel.

“It is not in our national security interest to get into a war with Iran unless that war is absolutely necessary to defend the United States,” Mr. Kaine said in a statement announcing the resolution....

Tehran has responded with barrages of missiles and drones that hit Israeli cities and towns, killing at least 24 people and wounding 592 others, according to the prime minister's office.

On the evening of June 12, Israel launched a series of major strikes against Iran.

The death toll is growing as Israel and Iran exchanged missile attacks for a third consecutive day on Sunday, and Israel is warning that worse is to come.

Israel unleashed airstrikes across Iran for a third day Sunday and threatened even greater force as some Iranian missiles evaded Israeli air defenses to strike buildings in the heart of the country.
