Egypt Hangs 15 for Terrorism, Stoking Fears Among IslamistsNY Times, Dec 26, 2017, NOUR YOUSSEF
CAIRO — The Egyptian authorities hanged 15 men on Tuesday for an attack in the Sinai Peninsula in 2013, the start of an Islamic insurgency that the military-dominated government has been battling ever since.
