Sunni insurgents who have rapidly taken over northern parts of Iraq. have released photos that appear to show their fighters carrying out a massacre of Iraqi troops.
We warn you - some of the images you're about to see are disturbing.
An independent body has not yet confirmed the validity of the photos, however, an Iraqi military spokesman says they are authentic.
The photos were uploaded on Saturday, on a militant website for the Islamic State of Iraq and the Levant, or ISIS.
The military said the images showed around one-hundred-70 Iraqi troops who had been captured and killed.
The government has reinforced defenses around the capital, however, a series of suicide bombings inside Baghdad killed over a dozen and left more than 40 injured.
This as ISIS militans seized the northern city of Tal Afar, which according to officials is a strategic location near the Syrian border.
Meanwhile Seoul's foreign ministry says all 13-hundred or so South Korean nationals in Iraq are currently in regions that are considered relatively safe.
The South Korean government has also formed a special task force to monitor the safety of its citizens in the country, on a day-to-day basis.
