Comprehensive Operation – Sinai 2018

Comprehensive Operation − Sinai 2018 (Arabic: العملية الشاملة − سيناء 2018) is the code name of a large counter-terrorism campaign conducted by the Egyptian Armed Forces and the Interior Ministry. The operation was initiated on February 9, 2018, and focuses on northern and central Sinai and parts of the Nile Delta. It mainly targets Islamist insurgents, as well as "other criminal activity that affects national security and stability", according to the Armed Forces press statement that announced the start of the campaign.

Following the Al-Rawda mosque attack of late November 2017, the deadliest of its kind in Egypt's modern history, President Abdel Fattah el-Sisi gave the country's main security institutions a three-month deadline to secure the Sinai, a region that has witnessed an insurgency since the start of the Egyptian revolution of 2011. Security preparations for COS 2018 were reported from as early as January.
