The US Department of State notes that a joint statement issued by more than 60 countries on August 15 says Afghans and international citizens who want to leave Afghanistan must be allowed to depart and added that airports and border crossings must remain open.

The U.S. government and countries including Australia, Canada, France, Germany, Italy, Japan, Republic of Korea, Qatar and the UK said in a joint statement that "those in positions of power and authority across Afghanistan bear responsibility - and accountability - for the protection of human life and property, and for the immediate restoration of security and civil order."

It added that "the Afghan people deserve to live in safety, security and dignity. We in the international community stand ready to assist them."

Recall, Afghanistan President Ashraf Ghani fled the country Sunday afternoon after Taliban militants entered Kabul and sought the surrender of the government.  The Taliban militants took control of the presidential palace in Kabul as U.S.-led forces departed and Western nations scrambled on Monday to evacuate thousands of their citizens.
