NATO foreign ministers are holding an emergency video conference later today to discuss the unfolding crisis in Afghanistan.
The alliance's former deputy assistant secretary-general Jamie Shea expects NATO to agree on a plan to coordinate all of these evacuations and to get them under control.

Shea has said.
