A total of 12 Egyptian soldiers were killed while others were injured in what is suspected to be an Islamic State (IS) extremist group attack on an army checkpoint in the Egyptian province of Sinai on Friday, media reported, citing sources. According to the Daily Star news outlet, a group of gunmen attacked the checkpoint located 25 miles away from the Egyptian town of Bir al-Abd in central Sinai with assault rifles and heavier weapons. Sinai became the center of media attention when an Airbus А321 plane, operated by the Russian airline Kogalymavia and en route from the Egyptian resort of Sharm El-Sheikh to St. Petersburg, crashed in the Peninsula as a result of an explosion on board on October 31, 2015. All 224 people on board the plane were killed. In 2014, Sinai’s indigenous militants pledged allegiance to the IS group outlawed in many countries, including Russia and the United States. The self-proclaimed Wilayat Sinai has subsequently claimed responsibility for a number of deadly attacks in the area.
