Prince Nayef bin Abdul Aziz said, "Bin Laden is the agent of a certain party, no doubt."
Nayef did not identify the suspected party, the daily newspaper Okaz reported Monday.
"The threat of terrorism in the kingdom persists, but the security forces are even stronger in their bid to combat it and eradicate it altogether," Nayef said.
"The shadow of terrorism will continue to exist as long as the sick and deviating minds are not eradicated and uprooted," he said, commenting on bin Laden's call to his followers to attack oil installations in Iraq and Gulf countries.
Nayef said that the Saudi government would hold an international anti-terrorism conference Feb. 5.
More than 100 people have been killed and dozens wounded in terrorist attacks that have swept Saudi Arabia over the past two years.
