In its first policy outline on antiterrorism measures, the National Police Agency called Thursday for new legislation to prevent terrorist attacks and improve the capability of police to respond to nuclear, biological or chemical attacks.

The NPA said it plans to work with other government agencies to draft legislation to fight terrorism and strengthen immigration control. It hopes to implement the policies within two years.

The NPA said the use of fingerprints and other biometric information is crucial in maintaining port control. It also hopes to introduce sky marshals.

To respond to emergency situations, the NPA plans to boost the capacity of police units designed to respond to nuclear, biological and chemical terrorism and of the special assault team that is mobilized when concrete information about a potential terrorist attack becomes available.
