United Nations ? The al-Qaida terror network is determined to use chemical and biological weapons and is restrained only by the technical difficulties of doing so, a U.N. expert panel said in a confidential report.

Sanctions on supporters of al-Qaida and Afghanistan’s former Taliban rulers appear to be too limited to prevent them from obtaining weapons and explosives, said the report, obtained Friday by The Associated Press.

The only thing holding al-Qaida back from using chemical and biological weapons “is the technical complexity to operate them properly and effectively,” the report said.
