A terrorist attack is an act of violence intended to create fear and panic among people. These attacks are often carried out by individuals or groups who want to promote a specific ideology or cause. They can target civilians, government buildings, or public events, and may involve weapons, explosives, or other means to inflict harm. The impact of terrorist attacks can be devastating, leading to loss of life, injuries, and widespread fear. Communities affected by such violence often struggle to recover, and governments may implement new security measures to protect citizens. Notable examples include the September 11 attacks in the United States and the 2015 Paris attacks in France.
