ROME (AFP) - Fighting global terrorism as well as the scourge of piracy calls for stronger cooperation among G8 nations, the bodys interior and justice ministers said Saturday. Despite some successes, terrorism is still one of the most serious threats to international security, the ministers from the Group of Eight rich nations said in a final statement after three days of talks near Rome. Our assessment of the threat shows that international terrorist groups maintain a significant offensive capability and demonstrate considerable organisational flexibility, they said. Extremists have shown they can recruit and radicalise their followers, which is a cause of great concern, which they said calls for closer monitoring of these groups and the channels they use to spread extremism. The counter-terrorism cooperation between G8 nations is essential, stressed the joint statement by the justice chiefs of Britain, Canada, France, Germany, Italy, Japan, Russia and the United States. The exchange of information on the movement of funding to finance terrorist group is a major example of such cooperation, said Italy Justice Minister Angelino Alfano when presenting the final communique. According to Interpols special anti-terrorism taskforce, there is a database of more than 8,000 suspects linked to terrorist activists and a network of nearly 200 contact officers in more than 100 countries. The head of the global police organisation brought to the G8 ministers attention the rising scourge of piracy on the seas, especially off the east African coast of Somalia, saying law enforcement was the missing link in combating this organised crime. There is clearly a need for a common international strategy that includes a law enforcement element to combat maritime piracy and armed robbery at sea, said Interpol Secretary General Robert K. Noble in a statement. Right now, we are in a situation in which there are pirates in custody while others have been arrested and released, but there is no central system in place for collecting, exchanging and processing data to help connect the dots, Noble said, suggesting the creation of an investigative prosecutorial taskforce. These pirates are organised criminals targeting victims, taking them hostage and using extortion to get money - we must therefore follow the money trail to strike a blow at the economic interests of this type of organised crime, he added. The G8 justice ministers agreed that steps must be taken to deprive the pirates of the proceeds of their criminal activity, their statement said. They also encouraged countries affected by piracy - either due to ships flying their flag being targeted, or their nationals being crewmembers or passengers on held ships. It noted that cooperation between states capturing pirates and those able to prosecute them plays a valuable role in counter-piracy efforts. In a separate declaration, the ministers urged tougher measures to combat the heinous crime of the sexual exploitation of children. They condemned all forms of exploitation including travelling sex offenders and child pornography on the Internet. While hailing G8 initiatives and cooperation in this area, they pointed to considering other aggressive measures such as a blacklist of websites containing child pornography and blocking navigation to paedophile sites.
