The doctors were executed after they refused to treat the terrorists.

Islamic State militants have executed 10 doctors who refused to treat wounded members of the terrorist organisation.

The jihadists sustained injuries while fighting in the Hammam al-Alil area and required medical treatment. However, the doctors were unwilling to support the terror group's activities, and refused to treat them. They were shot in the head for their defiance.

Graphic photographs of their final moments were released on social media, while Al-Sumaria satellite television reported the details of the doctors' murders in the northern Iraqi desert.

Local official Mowaffaq Hamid al-Azawi described the city of Mosul as an open-air prison, where residents are subjected to barbaric acts of torture at the hands of the IS terrorists.

IS fighters routinely carry out such horrific executions in accordance with their radical interpretation of Sharia law.

A recent spate of merciless killings have shocked the world. On March 30, horrific images were released showing Islamic State militants stoning a blindfolded and bound man and woman to death in Iraq. The couple were sentenced to death for having sex before marriage.

On March 24, thousands of protesters took to the streets in Kabul to demonstrate following the murder of a 27-year-old woman who was accused of burning the Koran.

The news of the latest executions comes as the jihadis executed 60 Sunni tribal fighters in Iraq's Anbar province after ISIS militants accused them of collaborating with the Iraqi security forces.

Radicalised westerners fighting for ISIS have been responsible for committing ever brutal atrocities in order to increase their ranking in the Jihadi hierarchy.

European militants are marginalised and are forced to take extreme measures to prove their loyalty to the terrorists cause, in a bid to make their name in Syria and Iraq.

A Syrian man who was detained for six months inside an IS jailed in Al Bab 30km north east of Aleppo, told The Times: "They [the foreign fighters] come ­expecting a heaven and when they see the reality they are shocked. There are two ways to prove your allegiance to IS: either by getting married or by carrying out the punishments," he explained. "The ­foreign fighters and the ­Syrians treated us the worst because they are the lowest in Isis."

British terrorist Jihadi John, who was identified as Mohammed Emwazi, is notorious for his brutality. He is responsible for the beheadings of several British and US hostages including British aid workers Alan Henning and David Haines, James Foley and Steven Sotloff from the US, and Japanese reporter Kenji Goto, as well as numerous Syrian soldiers.

The savage beheadings have been videoed and circulated via social media.

Emwazi apologised to his parents after being unmasked as ISIS executioner 'Jihadi John', but has not expressed any remorse for his role in the barbaric killings.
