The US naval base at Bahrain has been emptied of warships, satellite images released online yesterday reveal.

The specific images, analyzed by the Associated Press, appear to show that there are no longer any ships anchored outside the headquarters of the US Navy’s 5th Fleet in Bahrain as attacks between Israel and Iran continue. The images show the main dock without any ships.

Shipbreaking is a common safety technique used by navies around the world in times of unrest. Iran has threatened to target U.S. military installations in the region, though so far there have been no attacks since the start of the Israeli campaign against Iran on Friday.
