Iran's military has vowed a "decisive response" after the US struck three nuclear sites on Saturday. BBC Verify details how the attack unfolded. Direct US involvement in the conflict could provoke an even more momentous response from Iran, writes Lyse Doucet - but each move is risky. The US has asked China to stop Iran from closing the Strait of Hormuz, a crucial shipping route. US President Donald Trump has also raised the prospect of "regime change" in Tehran – a message that, notes North America correspondent Anthony Zurcher, adds risks for US troops in the region who could be a target of Iran's possible retaliation. For now, Iran has launched missiles at Israel, which has also continued to strike targets in the country.
