Egyptian police killed 11 terrorists in a shootout in North Sinai's Arish, an informed source told MENA news agency. Police forces had received information that a group of “terrorist elements” were using a deserted building as a hideout, MENA reported the source as saying, and were planning and carrying out hostile operations. The hideout was located in the “El-Salaima" area, which is adjacent to the Arish police station road. The raid was carried out based on intelligence obtained by the National Security Agency, which indicated that the suspects began shooting at police forces. Three automatic rifles, a sniper rifle, a cartridge gun, ammunition and improvised explosive devices were found at the site. The Supreme State Security Prosecution is conducting an investigation into the incident, the source said. The armed forces on Sunday issued their 26th communique on recent developments in Operation Sinai 2018, a comprehensive military and police counter-terrorism operation which began in February, announcing that in recent days they had killed 52 militants and arrested 49 others.
