The terror group ISIS-K has claimed responsibility for the blasts outside the Kabul airport. Thirteen U.S. soldiers were among the victims as most were Afghan civilians seeking evacuation.

How will this affect the ongoing evacuation? Who is ISIS-K? What is their connection - if any - to the Taliban? How is the Taliban reacting to the attack?

To find out more, we've invited Yang Xiyu, senior fellow of China Institute of International Studies; Peter Kuznick, professor of history in American University; Zmaryalai Abasin, correspondent in Kabul; and Muhammad Amir Rana, director of Pakistan Institute for Peace Studies.
