Cairo - The terrorist attack in the Egyptian North Sinai Governorate late Sunday led to the death of five policemen, medical and security sources confirmed. Law enforcement workers were attacked on Sunday evening when they were about to leave for a vacation. The law enforcement reportedly believes that the attackers were linked to Ansar Bait al-Maqdis terrorist group, which in 2014 pledged allegiance to the terrorist 'Islamic State, also known as ISIS and Daesh, an extremist group outlawed in many countries. On January 11, four policemen were killed in an attack on a police station in North Sinai, carried out by the same terrorist group. Ansar Bait al-Maqdis emerged after the 2011 Egyptian revolution, which forced then President Hosni Mubarak out of power after an over 30-year rule. The militants aim to topple Egypt's current government.
