Syria's al-Qaeda offshoot Nusra says it killed Lebanese soldier

Syria's al-Qaeda offshoot Nusra said on Friday it killed a captive Lebanese soldier in retaliation for the arrest by Lebanese authorities of women identified as wives of Islamist militants.

The soldier was one of more than two dozen members of the security forces taken captive by militants affiliated to the Nusra Front and Islamic State when they staged an attack on the Lebanese border town of Arsal in August.
