A reliable security source told Al-Anba no Saudi officials are taking part in the interrogations of the detained suspects. The source said Saudi officials are coordinating with their Kuwaiti counterparts in the investigations in accordance with the security accord between the two countries. The daily also said explosive experts safely removed a rocket propelled grenade (RPG) found in a yard near Kuwait Entertainment City in Doha. A security source told the daily the ordnance might belong to the retreating Iraqi Army after Kuwait's Liberation in 1991. It added that the RPG may have been left in the yard by someone who feared being arrested with it in his possession.
