The US military says it has completed a "heavy wave" of strikes against Iran in retaliation for Tuesday's attempted ballistic missile attacks on American forces. Iranian state media said the latest strikes had killed three people, including a two-year-old child, on Qeshm island, while other locations were also hit in the south and west of the country. The latest hostilities come on a week that has seen the conflict expand, with the first publicly announced joint US-Saudi strikes targeting Iranian proxies in Iraq. Iran and the US have engaged in escalating strikes and counter-strikes since a ceasefire in April, aimed at pausing the months-long war, fell apart in June. For days, both sides halted strikes as talks apparently restarted in hopes of some type of diplomatic solution.
