Within hours of the assassination, Lebanese prosecutors issued warrants for the arrest of six Australian nationals who flew out of Beirut to Sydney, Australia three hours after the explosion claiming that seats occupied by the men had tested positive for traces of explosives, and that they were traveling without luggage. The Australian Federal Police interviewed ten individuals in Sydney upon the arrival of the flight, and found the men they questioned did have luggage. Although Sydney airport security sniffer dogs trained to find explosives did react to aircraft seats occupied by the men, test swabs taken from three of the men by the Australian Federal Police tested negative for explosives. Within 48 hours, the Australian Federal Police absolved the six of any involvement in the assassination, giving little credibility to claims of the Lebanese officials.
