 When news of the agreement reached Alexandria, the people of the city rioted.Comanus and Cineas rejected the agreement, rejected Ptolemy VI's authority and declared Ptolemy VIII the sole king (Cleopatra II's position remained unchanged).Antiochus responded by placing Alexandria under siege, but he was unable to take the city and withdrew from Egypt in September 169 BC, as winter approached, leaving Ptolemy VI as his puppet king in Memphis and retaining a garrison in Pelusium.
