U.S. officials are concerned that Israel will not warn them before taking military action against Iran's nuclear facilities, a senior U.S. military official said Friday.

The official, who asked to remain anonymous, told the CNN network that although in the past, U.S. officials thought they would receive warning from Israel if it did take military action against Iran, "now that doesn't seem so ironclad."

The U.S. is "absolutley" concerned that Israel is preparing an attack on Irans nuclear facilities, and this concern is increasing, CNN reported the official as saying.

The U.S. has increased its watchfulness of Iran and Israel over the past few weeks, U.S. Central and European Commands, which watch Iranian and Israeli developments respectively, are increasingly vigilant at this time, according to the official, and a second military official who also spoke with CNN.

The military official emphasized that the U.S is concerned about the risk a strike against Iran could pose for American troops in Iraq and in the Persian Gulf, according to the CNN report.

The official also said that the U.S. does not intend to follow a military action against Iran, CNN said.

On Friday, President Shimon Peres said that he believes Israel and the world may soon take military action against Iran. His comments followed
