The bodies of the teens, Eyal Yifrach, Gilad Sha'ar and Naftali Fraenkel, were discovered the previous day in a field near Karmei Tzur in the West Bank, and are brought to rest in a joint funeral ceremony at the Modiin cemetery. The three teenagers had been missing since June 12, while hitchhiking in the West Bank, and were presumed to have been abducted by terrorists. Photo by Nati Shohat/Flash90
