A senior military figure in the Lebanese Shia Islamist group Hizbollah is reported to have died in Syria.
Hizbollah says Ali Hussein Nassif was buried in the Bekaa valley earlier this week.
It says he was killed "performing his jihadist duty", but did not say where.
Rebels say he and several of his men had been killed in an ambush by the Free Syrian Army.
Other reports say they died in clashes on the border.
The BBC reports there has been no confirmation that he was Hizbollah's commander in Syria.
The United States has accused Hizbollah of "providing training, advice, and extensive logistical support" to the Syrian government, an allegation the group has denied.
