Islamist extremist groups are organizations that use a radical interpretation of Islam to justify violence and terrorism. They often seek to impose their strict beliefs on society, aiming to create a political system based on their interpretation of Sharia law. These groups can vary in size, structure, and goals, but they generally reject democratic processes and promote armed struggle. Some well-known Islamist extremist groups include Al-Qaeda and ISIS. These organizations have been involved in numerous attacks worldwide, targeting civilians, government institutions, and military forces. Their actions have led to widespread condemnation and efforts by various countries to combat their influence and prevent further violence.
