Syria has arrested a Saudi official in connection with the assassination of top Hizbullah commander Imad Mughniyeh, Iran's semi-official Fars news agency reported Tuesday. The agency quoted an Iranian source as saying a high-ranking defense official in Saudi Arabia's embassy in Damascus was arrested by Syrian security forces. The source said Israel masterminded the assassination, but the operation itself was carried out by locals with Syrian, Jordanian and Palestinian citizenships. These men bought or rented apartments near Mughniyeh's place of residence in Damascus and surveyed his activities from there, the source said. The Saudi official, he said, was connected to a Syrian woman in whose name were registered the two explosives-laden cars used to kill Mughniyeh. Fars also claimed that the results of the Syrian inquiry should have already been published, and blamed the delay on pressure from Gulf states including Kuwait and Saudi Arabia.
