Multilateral collaboration and a crackdown on identification abuse are crucial to reducing transnational crimes and terrorist activities, justice and home affairs ministers from the Group of Eight industrialized nations declared Friday.

"It is necessary to continue to support and strengthen our concerted counterterrorism efforts, to share the knowledge and experience that the G8 states possess," the ministers said in a statement after their two-day meeting in Tokyo.

Pointing out the potential for even people unaffiliated with terrorist organizations to become "radicalized" and commit acts of terrorism, the summary also addressed the need to enhance "community policing efforts" to detect such individuals at an early stage.
