David Haines, the British hostage being held by Islamic State, IS or ISIS, has been beheaded in a new video released by the terrorist group, it has been reported.

In the video, produced by the terrorist organisation, the same British accented man who is suspected to have previously killed David Foley and Steven Sotloff has been seen killing the British aid worker David Haines. The 44-year-old aid worker, and a father of two, was being held by IS, who had threatened to kill him next in an earlier video depicting a reporter’s beheading.

The video, which was released last night, showed Mr Haines being killed in the same fashion as the previous two murder videos released by the militants of IS.

Following the release of this video the Prime Minister tweeted “The murder of David Haines is an act of pure evil. My heart goes out to his family who have shown extraordinary courage and fortitude. We will do everything in our power to hunt down these murderers and ensure they face justice, however long it takes.”

As with the previous two videos the murders forced Mr Haines to make a statement attacking his own government. In this case, Haines was made to say “I would like to declare that I hold you David Cameron entirely responsible for my execution. You ventured voluntarily into a coalition with the United States against the Islamic State, just like your predecessor Tony Blair. Following a trend amongst our British prime minister who can’t find the courage to say no to the Americans. Unfortunately it is we, the British public, that will in the end pay the price for our parliament’s selfish decisions.”

Following this statement made by the victim the British accented jihadist, nicknamed Jihadi John, who is the suspected killer in the previous two videos stated “This British man has to the pay the price for your promise, Cameron, to arm the Peshmerga against the Islamic State. Your evil alliance with America which continues to strike the Muslims of Iraq and most recently bombed the Haditha Dam will only accelerate your destruction and playing the role of the obedient lapdog Cameron will only drag you and your people into another bloody and unwinnable war”
After the act of murder is committed the militant added that “If you, Cameron, persist in fighting the Islamic State then you like your master Obama will have the blood of your people on your hands.”

Tributes to David Haines have been flowing in fast, following the release of this video less than 24 hours ago. The Prime Minister has called Haines “a British hero” and praised the strength of those in his family calling it “extraordinary courage”. An emotional Cameron, following a meeting of the emergency committee Cobra, said that they were ready to take “whatever steps necessary” to help an international push to “destroy” IS. He also reiterated his statement on twitter saying he would “hunt down those responsible and bring them to justice no matter how long it takes.” Cameron did however make sure to emphasis the point that these men were “not Muslims, they are monsters” in an effort to quiet the anti-Islamic sentiment which may have developed as a result of this latest attack against one of our citizens.

In a statement made through the Foreign Minister, David Haines’ brother Mike said “David was a good brother, there when I needed him and absent when I didn’t. I hope that he felt the same way about me. He was, in the right mood, the life and soul of the party and on other times the most stubborn irritating pain in the ass. He would probably say the same about me.” Speaking of his brothers family Mike stated “He married his childhood sweetheart Louise and in the due process of time had a wee lass Bethany. He was, and no doubt wherever he is, exceptionally proud of Bethany.”

Speaking of his humanitarian work Mike Haines stated, “David served with the UN in the Balkans, helping people in real need. There are many accolades from people in that region that David helped. He helped whoever needed help, regardless of race, creed or religion. During this time David began to decide that humanitarian work was the field he wanted to work in.”

Finally in regards to what he meant to his family “David was most alive and enthusiastic in his humanitarian roles. His joy and anticipation for the work he went to do in Syria is for myself and family the most important element of this whole sad affair. He was and is loved by all his family and will be missed terribly.”
