David Cameron chairs Cobra meeting on IS threat

Authorities in France have named a second Frenchman in a video showing the killing of prisoners by Islamic State militants as Mickael Dos Santos, 22.

Muslim convert comes from an eastern Paris suburb. The other French militant was named as Maxime Hauchard, a convert from Normandy, earlier this week.

David Cameron was briefed today about the ongoing hunt for Islamic State (IS) militants responsible for the murders of Western hostages.

The Prime Minister chaired a session of the Government's Cobra committee where he was updated by intelligence chiefs about their progress in trying to track down militants responsible for killing westerners including US hostage Peter Kassig.

Cameron has vowed that the terrorists will face "justice" after videos have emerged in recent weeks of the latest IS atrocities including the beheading of kidnapped Westerners and captured Syrian soldiers.

The father of a British man, previously thought to be one of the unmasked Isis killers featured in a propaganda film showing the killing of American aid worker Peter Kassig, has said the man in the video is not his son.

Ahmed Muthana, told The Times: "I looked at the line-up and I didn't recognise my son. One of them looked like him but the eyes and nose are different."

Video analysis commissioned by the paper also suggested that when compared to previous photos of student Nasser Muthana the man in the video did not appear to be the same person.

David Cameron will chair the Government's Cobra emergency committee today to assess progress in the fight against Islamic State (IS).

The Prime Minister vowed that the terrorists would face "justice" after video footage surfaced apparently showing the murder of US hostage Peter Kassig.

Senior intelligence and military officials are expected to attend the Cobra meeting.

The parents of murdered US aid worker, Abdul-Rahman Kassig - also known as Peter- have spoken to the media for the first time since the death of their son was announced.

In a short statement, Ed and Paula Kassig said:

“Greater love hath no man than this: than to lay down his life for another.”

A while ago, we were informed that our beloved son, Abdul-Rahman, no longer walks this earth. Our hearts, though heavy, are held up by the love and support that has poured into our lives these last few weeks.

Paula Kassig:

One of Abdul-Rahman’s teachers, the mother of some of his friends, wrote before his slaying:

“If a person can be both a realist and an idealist, then that’s Peter. Peter has earned the right to be both. In 26 years, he has witnessed and experienced first hand more of the harsh realities of life than most of us can imagine. But, rather than letting the darkness overwhelm him, he has chosen to believe in the good – in himself and in others…. Peter’s life is evidence that he’s been right all along; one person can make a difference. “

Our hearts are battered, but they will mend. The world is broken, but it will be healed in the end. And good will prevail as the One God of many names will prevail.

Ed Kassig:

Please pray for Abdul-Rahman, or Pete if that is how you knew him, at sunset this evening. Pray also for all people held against their will in Syria, Iraq, and around the world.

Lastly, please allow our family the time and privacy to mourn, cry - and yes, forgive - and begin to heal.
