South Vietnamese forces follow after terrified children, including 9-year-old Kim Phuc, center, as they run down Route 1 near Trang Bang after an aerial napalm attack on suspected Viet Cong hiding places on June 8, 1972. A South Vietnamese plane accidentally dropped its flaming napalm on South Vietnamese troops and civilians. The terrified girl had ripped off her burning clothes while fleeing. The children from left to right are: Phan Thanh Tam, younger brother of Kim Phuc, who lost an eye, Phan Thanh Phouc, youngest brother of Kim Phuc, Kim Phuc, and Kim's cousins Ho Van Bon, and Ho Thi Ting.
