Asian markets plunged while oil prices briefly hit five-month highs on Monday as investors anxiously awaited Tehran’s next move after the United States joined Israel in attacking Iran’s nuclear facilities, escalating the Middle East crisis.

Iran on Sunday said its attacks on Israel will end once the Jewish state halts its military campaign against the Islamic Republic, adding its response had been based on self-defence.

Trump’s decision to order US forces to attack three key Iranian nuclear installations may have sabotaged the Islamic Republic’s known atomic capabilities, but it’s also created a monumental new challenge to work out what’s left and where.
