Countries around the world are taking measures to evacuate their citizens from Israel and Iran as the two nations enter the seventh day of their air war and airspace in the region remains closed.

Global Affairs Canada said Thursday evening that almost 5,000 people in Iran are registered with the government, a number that has gone up by about 1,500 since Monday.

The aerial war between Israel and Iran has been playing out in the skies over the Levant, prompting concern in each country about its effects on internal stability and their strategic position.Iraq has condemned the Israeli strikes on Friday that ignited the war.
