LONDON – Now it’s Britain’s turn to mourn.
British aid worker David Haines has been beheaded – like two American journalists before him – and the Islamic State group is threatening to kill a fourth captive.
A grisly video released by the group showing Haines’ body both mocks the West and raises the pressure on Western leaders. It concludes with a death threat against British hostage Alan Henning, shown in the same kind of orange jumpsuit the other three were wearing when they were killed.
Haines’ family asked that he be remembered for devoting his life to helping civilians caught in deadly conflicts.
Haines is the third Westerner beheaded in recent weeks by the Islamic State group, which has seized large parts of Syria and Iraq and, according to Cameron, poses a “massive” threat to the rest of the Middle East.
“They are killing and slaughtering thousands of people – Christians, Muslims, minorities across Iraq and Syria,” Cameron said after an emergency meeting with military and security chiefs.
“They boast of their brutality. They claim to do this in the name of Islam. That is nonsense. Islam is a religion of peace. They are not Muslims; they are monsters,” he said.
Cameron said the group is planning attacks against Britain and the rest of Europe, and that Britain has to step up its counterterrorism efforts.
Britain will support U.S. military efforts against the Islamic State group by using British forces to help with logistics and intelligence gathering, he said, but will not send ground troops.
The tall, masked figure in the video appears to be the same man who appeared in earlier videos announcing the killings of Americans James Foley and Steven Sotloff.
The video opens with footage of Cameron condemning the Islamic State group. The man with the knife then appears and condemns Britain’s support of U.S. action against the group and says the captive must pay with his life.
The Islamic State group’s videos have all followed a similar script, with the extremist dressed in black – only his eyes visible – and the victim dressed in an orange jumpsuit. They are in a desert landscape with no obvious identifying landmarks.
Each has also included a threat against another captive briefly shown on camera.
Britain’s Foreign Office initially asked the press not to identify Henning as the captive shown on camera, but it dropped this request Sunday with his family’s approval. The family also distributed a photo of Henning.
His brother, Mike Haines, said David approached his humanitarian work with boundless enthusiasm.
“He helped whoever needed help, regardless of race, creed or religion,” he said.
David Haines was kidnapped in Syria in March 2013 while working for the French aid group Agency for Technical Cooperation and Development to help victims of the fighting.
