Russia, Germany and Britain urged countries in the Middle East to show restraint and Israel said it was preparing to “meet all its security needs” in a region on edge over an Iranian threat to strike Israel, Reuters reports.

The German airline Lufthansa, one of only two Western carriers flying to Tehran, extended a suspension of its flights to the Iranian capital and Russia warned against travel to the Middle East.

British foreign minister David Cameron said he had made clear to Amirabdollahian that Iran should not draw the Middle East into a wider conflict.

“I am deeply concerned about the potential for miscalculation leading to further violence,” Cameron said on X.
