American and Israeli forces have carried out strikes on cities across Iran, in what US President Donald Trump has described as "major combat operations".
Trump has called for the Iranian people to rise up and government forces to surrender following what Israel called a "preemptive attack".
In response, Iran's Revolutionary Guard Corps (IRGC) said in a statement it was targeting US bases and assets across the Middle East as part of operation "Truthful Promise 4",
This comes after weeks of threats and negotiations over Iran's nuclear programme.
Here is how the international community is reacting.
