EAST Yorkshire's Muslim community has condemned those who beheaded a Holderness-born aid worker.
The Foreign Office said it is almost certain the video released by Islamic State (IS) militants showing David Haines being beheaded is genuine.
The leader of Hull Mosque and Islamic Centre Imam Hafiz Salik insists IS, also know as ISIL or Isis, has no place in the Muslim world.
Imam Salik said: "I totally condemn these actions by IS and we have no support for the organisation.
"They are doing these terrible things under the name of Islam but they are working against our religion.
"In our religion, if you save a life you serve all of humanity but if you kill a person you kill all of humanity.
"Mr Haines was an aid worker who had no weapons and was fighting no one. IS has broken the rules of Islam.
"It is such a shame a man born in East Yorkshire has died this way but this is the same for anyone anywhere in the world.
"Our thoughts go out to Mr Haines' family."
Beverley and Holderness MP Graham Stuart has also paid tribute to Mr Haines, who was kidnapped from a Syrian refugee camp last year.
Mr Stuart said: "Holderness man David Haines was an aid worker determined to bring stability, justice and prosperity to the people he served.
"He, less than anyone, deserved to be murdered in this brutal way by people whose perverted religious views need both to be rejected and resisted.
"We can be proud that someone born in East Yorkshire was prepared to put himself in harm's way, not for personal gain or glory, but simply to serve people caught up in civil war and suffering unspeakable misery."
Mr Stuart believes IS needs to be tackled with diplomacy.
He said: "ISIL is not something that we can allow to grow and poison more minds, including those of British citizens, as it spreads not only its sphere of influence but its propaganda reach.
"Instead, it must be confronted and overcome by the widest possible coalition, including Sunni states.
"Diplomacy, intelligence and military might must be used to help the people of the Middle East take responsibility for and lead efforts to eradicate ISIL and all it stands for.
"David Haines didn't hesitate to provide help for the area and, in his name, we should do the same."
Father-of-two Mr Haines, 44, was born in Holderness before moving to Perth. He has been widely praised for his humanitarian work.
In the video, a militant with an English accent blames the death on Mr Cameron for "arming the Peshmerga (Kurdish armed forces) against the Islamic State". It includes a threat to kill another British hostage, who was last night named as Alan Henning, of Greater Manchester.
The release of the video came just hours after Mr Haines' family had made a direct appeal to IS militants – who have already murdered two American journalists – to contact them.
Mr Haines worked with the Royal Mail before joining the RAF as an aircraft engineer.
He married his childhood sweetheart Louise and had a daughter, Bethany.
After they divorced, Mr Haines met and married his second wife Dragana and they have a four-year-old daughter called Athea. The couple lived in Croatia.
In a statement released by the Foreign Office, Mr Haines' brother Mike paid tribute.
He said: "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 is loved by all his family and will be missed terribly."
