SINGAPORE (Reuters) - Al Qaeda and groups linked to it remain the world's biggest security threat despite the killing of Osama bin Laden, the head of Interpol said on Tuesday.

Airlines and other forms of public transport are most at risk, with terrorists using fraudulent passports to travel undetected an area of particular concern, Interpol Secretary General Ronald Noble told reporters on the sidelines of an aviation meeting in Singapore.

"Even before bin Laden was captured and killed, the biggest threat was not only al Qaeda but al Qaeda-affiliated terrorist groups around the world," he said "I think that remains the biggest threat now as it was before his death.

"The airline and air industry continues to be a prime target for terrorists, but we've seen from recovered intelligence etc that they are also focusing a lot on mass transit. But airlines continue to be a special target."
