Israel's air force achieved a "remarkable feat," said William Freer, a research fellow for national security at the U.K.-based Council on Geostrategy.

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

Smoke and missiles have lit up the skies in Israel and Iran in a fierce standoff triggered by fears over Tehran’s expanding nuclear program. Since June 13, hundreds of military strikes have been exchanged as the two nations remain locked in a conflict that shows no signs of abating.

Iran and Israel intensified strikes on each other's infrastructure and territory over the weekend after Israel launched a surprise assault on its long-time enemy's military leadership and nuclear program.

A dramatic spike in the potential for all-out war between Israel and Iran would typically be expected to spark an immediate and strong rally in the U.S. dollar, with investors seeking the safety and liquidity of the world's reserve currency.
