Rival Shiite and Sunni groups kidnapped Syrians and staged violent riots near the Syria-Lebanon border on Thursday, August 16, as the bloody conflict pushed neighboring Lebanon into deeper unrest, The Wall Street Journal reported. An obscure Shiite armed group said it had captured 10 members of the rebel Free Syrian Army operating in Lebanon on Thursday. Separately, the Meqdad family, a powerful Shiite clan that had taken 40 Syrians hostage on Wednesday, vowed to continue to target Syrians perceived to sympathize with the country’s rebels until they released a Meqdad family member currently held as a hostage. In Lebanon’s eastern Bekaa Valley, violent protests erupted when Sunni Islamists—supporters of the Syrian opposition—blocked the main highway and attacked a car of a Lebanese journalist. The group was apparently seeking to retaliate against Shiites and family members of the Meqdad clan.
