Sheik Omar Mohammed Bakri, who moved from Britain to Lebanon, appeared by video link at the meeting Thursday, the seventh anniversary of the Sept. 11 destruction of the World Trade Center in New York, The Daily Mail reported.

Saiful Islam, leader of a group called Salafi Youth for Islamic Propagation, told the group Britain and the United States "will not achieve security until our lands achieve security."

"Sheik Osama (bin Laden) warned America numerous times, it was because of their own arrogance, because they thought they are a superpower and nobody could match them, that Sheik Osama taught them a lesson -- a lesson they still haven't learned," Islam said.

About 100 people attended the meeting.
