As Israeli troops during the second Israeli invasion of Lebanon prepared to enter Beirut. Jiryis, anticipating the risk of seizure, had the Center's collection of rare and highly valuable documents, and all files pertaining to sensitive information, such as personnel files, packed away in two suitcasesand later shipped out to safety from Lebanon. When the invasion got underway, the PRC was targeted in two earlier car bombings, in July and August 1982. On July 13, a car positioned in a parking lot adjacent to the Center exploded, but caused only minor damage. On 18 August, P.L.O. officers detected another car packed with explosives parked in front, and managed to evacuate people from the vicinity before it exploded and wounded 4 people.
