Sirens have been heard in the Jordanian capital after the US and Israel launched a wave of strikes on Iran, AFP reports.

The public security directorate in Amman said the “meaning of the sirens will be as follows: three intermittent sirens mean there is a threat, and one siren means the threat has passed”.

“When you hear the three sirens, it is advisable to stay where you are and not move. If you are outside your home, you should take shelter in the nearest building until the threat has passed,” it added in a statement.
