In a move almost unthinkable only three years ago, Gulf Arab navies have held their first joint military exercise with Israeli warships, co-ordinated by the US Navy.
The five-day drill in the Red Sea involved warships from the United Arab Emirates, Bahrain, Israel and the US. It began last Wednesday and included boarding, search and seizure tactics "to help ensure freedom of navigation".
US Naval Forces Central Command said the training would "enhance interoperability between participating forces' maritime interdiction teams".
