Several US officials were quoted by the newspaper as saying that it seemed the drill was an effort to develop Israel's capacity to carry out long-range strikes and to show the gravity with which Israel views the Iranian nuclear issue.

More than 100 IAF F-16 and F-15 fighter jets took part in the exercise, which was carried out over the eastern Mediterranean and over Greece, the officials said.

The drill also included IAF rescues helicopters, said the officials, adding that the helicopters and refueling tankers flew more than 900 miles, which is approximately the distance between Israel and Iran's uranium enrichment plant at Natanz.
