KUWAIT (AP) _ The two Kuwaitis who attacked U.S. Marines were not acting alone and one of them headed a group planning more assaults on Americans, an Interior Ministry official said Friday.

However, no connection with Osama bin Laden's al-Qaida terror network has been established yet, the official said on condition of anonymity.

Questioning of some 60 suspects and witnesses since Tuesday's shooting that killed one Marine and injured another have led to a ``cell of around 15 people'' that was headed by Anas al-Kandari, one of the attackers, the official said.
