Sunni extremist groups are organizations that interpret Islam in a strict and militant way, often advocating for violence to achieve their goals. These groups typically follow a fundamentalist ideology, believing that their interpretation of the Quran and Hadith should be imposed on others. They often oppose both secular governments and other Islamic sects, particularly Shia Muslims. Some well-known Sunni extremist groups include Al-Qaeda and ISIS. These organizations have been involved in various conflicts and terrorist activities around the world, aiming to establish a society governed by their interpretation of Islamic law, known as Sharia. Their actions have led to significant violence and instability in many regions.
