This photo posted on a file sharing website Wednesday, Jan. 11, 2017, by the Islamic State Group in Sinai, a militant organization, shows a deadly attack by militants on an Egyptian police checkpoint, Monday, Jan. 9, 2017, in el-Arish, north Sinai, Egypt. An Israeli defense official said Wednesday that the country has developed a new policy in recent years to allow Egypt to quickly beef up its forces in the volatile Sinai peninsula as part of a shared struggle against Islamic militants. The comments came days after Egyptian President Abdel-Fatteh el-Sissi said there are about 25,000 Egyptian troops operating in Sinai. Arabic reads, "Clash with light arms with the remaining apostates left alive at the fire station checkpoint." (Islamic State Group in Sinai, via AP)
