• Iran says US ‘must receive a response’ after Trump’s strikes on nuclear sites

More than $10bn has been wiped from the Australian share market on opening after the US bombing of Iranian nuclear facilities, as traders react to worsening economic growth prospects.

The benchmark S&P/ASX200 fell below 8,460 points, back to near where it was at the start of June after holding above 8,500 points on Friday. It had closed at an all-time high of 8,592 on 11 June, days before Israel began its military strikes on Iran, but has fallen in six of the subsequent seven trading days.
