Lebanon army probes new Islamic State beheading claim

The Lebanese army is investigating photographs purportedly showing a second soldier who had been beheaded by the Islamic State, a military source said Saturday.

An apparent IS supporter posted a photo on Twitter showing a masked man wearing black, holding the severed head of a bearded young man over his body.

The corpse is lying in a pool of blood and, in the background, a man is holding up the black IS flag.

"The army has received the images, but we cannot confirm or deny whether they are authentic," said the source, speaking on condition of anonymity.

The image emerged four days after DNA testing confirmed that the body of a man whom militants had said they beheaded was that of Lebanese soldier Ali Sayyed.

Sayyed had been captured by militants from the al-Qaeda affiliated Al-Nusra Front and the IS, along with some 30 soldiers and police in the eastern town of Arsal last month.

They were seized during major fighting against militants who had flooded in from neighbouring Syria.

Earlier Saturday, the body of a Lebanese civilian kidnapped and killed by militants was handed over to his family in Arsal.

Kayed Ghadada was abducted last month after the battle, which killed 20 soldiers, dozens of militants and 16 civilians.

The fighting in Arsal was the most serious border incident since the Syrian conflict erupted in March 2011.

The militants have reportedly sought to negotiate the release of the hostages in exchange for Islamist prisoners held in Lebanese jails.

Lebanese officials have rejected holding talks on a possible prisoner swap, but have said Qatar is mediating negotiations on the issue.
