Several of them sustained injuries so visited local

Militants fighting for the Islamic State in Iraq have savagely executed 10 doctors who refused to treat wounded members of the terrorist organisation.

ISIS jihadis are understood to have been fighting local groups in the Hammam al-Alil area when several of them sustained injuries requiring medical treatment. When the doctors refused on the grounds they do not support the terror group's activities, the men were brutally murdered.

Details of the doctors' brutal murders in the northern Iraqi desert were reported by the country's Al-Sumaria satellite television network.

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

The news comes as the jihadis reportedly executed 60 Sunni tribal fighters in Iraq's Anbar province.

Members of the Al-Karableh, Albu Ubaid, Albu Mahal and Albu Salman tribes were brutally executed after paranoid ISIS militants accused them of collaborating with the Iraqi security forces.

Iraqi Army soldiers and the Iran-backed volunteer Shiite militias allied with the Iraqi regime have had great success in pushing ISIS out of key towns and villages recently.

Just last week the security forces liberated the city of Tikrit - the birthplace of Saddam Hussein and a strategically important area from which the Iraqi Army will look to recapture Mosul and eventually force ISIS out of the country altogether.

This morning U.S. Defense Secretary Ash Carter said the U.S. has made progress against ISIS in Iraq but cannot predict how long the fight will take.

Speaking at a joint news conference with his South Korean counterpart, Carter said he would not go so far as to say this is the beginning of the end for ISIS in Iraq.

ISIS' onslaught plunged Iraq into its worst crisis since the 2011 U.S. troop withdrawal from the country. The militants have also targeted Iraq's indigenous religious minorities, including Christians and followers of the ancient Yazidi faith, forcing tens of thousands from their homes.

Since then, ISIS has carved out a self-styled caliphate in the large area straddling the Iraqi-Syrian border that it now controls.

In early August, the United States launched airstrikes on the militant group in Iraq, in an effort to help Iraqi forces fight back against the growing threat by the IS militants, who still hold the northern Iraqi province of Ninevah and most of the western province of Anbar, in addition to small areas north of Baghdad in their hands, along with a large swath of land in neighboring Syria.
