Four Afghan doctors in Japan will join operations to support the growing number of Afghan refugees fleeing to Pakistan in the wake of the U.S.-led military strikes against their country that began Sunday.

The four, all brothers, are to meet Foreign Ministry officials today along with Japanese medical staff to arrange their departure. They work with the nongovernmental organization Japan International Friendship and Welfare Foundation.

Internist Kazem Ahmadyar, 48, and his brothers Asghar, 44, a pediatrician, Akbar, 42, a surgeon, and Jafar, 36, a medical staff coordinator, are originally from the central region of Ghazni.
