An al-Qaida-linked group in Syria says it has killed a Lebanese soldier it was holding captive.

The Nusra Front group says it shot dead Ali Bazzal on Friday night in retaliation for the Lebanese government's detention of the wives and children of militants.

Lebanese security officials this week said they have arrested a wife and child of the Islamic State group's leader, Abu Bakr al-Baghdadi. Authorities have also arrested the wife and two children of another Sunni militant commander in Syria, Abu Ali al-Shishani.

The Nusra Front announced the killing of Bazzal via its Twitter account. It published a photo purporting to show Bazzal being shot in the head.

There was no immediate confirmation of the news.

The two militant groups are holding around 20 Lebanese soldiers and policemen.
