Lebanese Shia group Hezbollah said on Saturday "takfiri groups" were responsible for a blast which killed the group's top military commander Mustafa Badreddine. "Takfiri" is a word used by the group to refer to hard-line, armed, Sunni Islamist groups. Hezbollah announced Badreddine's death on Friday and a military funeral was held for him on the same day in the group's stronghold in southern Beirut. http://english.ahram.org.eg/News/216780.aspx
