Terrorism has become one of the most severe crime problems facing the world. There are several factors that contributed to the rise of terrorism world wide.

Counterterrorism includes offensive measures taken to prevent, deter, and respond to terrorism. Within the emergency management, antiterrorism is a hazard mitigation activity and counterterrorism falls within the scope of preparedness, response and recovery.

According to Interpol, it constitutes a grave threat to individuals' lives and national security in their member states, and the organization has therefore made significant efforts to address this world wide concern.

Bio-technology is undergoing rapid evolution and is already proving difficult to manage. Bio-weapons threaten thousands of casualties in addition to other disastrous long-term consequences. Criminal networks can covertly transport lethal biological agents across borders, and terrorists have already proven that anthrax can be fatally deployed.

An effective biological weapon is potentially devastating and much easier to make and transport than a nuclear weapon. Bio-weapons are relatively safe for the terrorist. Pathogens (biological agents or germs) are virtually undetectable and can be brought reasonably easily into a country by an individual, where they can then potentially be propagated in large quantities.

Recognizing the imminent dangers represented by this lethal form of crime is the first step in countering the threat. Law enforcement agencies have a crucial role to play, with significant support from a range of counter-terrorism specialists, national and international governmental and non-governmental agencies, scientists and other academics. This will enable law enforcement agencies to take appropriate measures.
