A brother-in-law of al Qaeda in Iraq's former leader, Abu Musab al Zarqawi, has died while fighting for the Al Nusrah Front in Syria, Al Jazeera reported. And the jihadist replacing him as emir of an Al Nusrah subgroup has also served Zarqawi in Iraq.

Iyad al Tubasi, who is also known as Abu Julaybib, is thought to have been killed earlier this week in Daraa, a town in southwestern Syria near the Jordanian border. Al Tubasi is just the latest Zarqawi family member to have been killed on the battlefield or captured.
