NABATIYEH - Lebanese people attend a rally in the southern Lebanese town of Nabatiyeh on August 31, 2008 to mark 30 years since Shiite leader Mussa Sadr vanished without trace in Libya. Several thousand people joined this rally in Lebanon to mark the mysterious disappearance of Sadr, who founded the opposition Amal movement now led by parliament speaker Nabih Berri. Sadr, who would have been 80 this year, is still regarded by the Lebanese Shiite community as their key spiritual guide.
