The situation in Iraq is rapidly deteriorating as al-Qaeda-inspired insurgents from the Islamic State of Iraq and Syria (ISIS) and Kurdish militants continue to seize cities closer and closer to Baghdad. Here are videos that highlight the situation in Iraq and neighboring Syria.

Militants attacked government buildings in an area south of Mosul. This video shows the aftermath of the bombings. Seizures of key government establishments in Mosul and surrounding regions enabled ISIS's capture of the city, said to be one of the largest in Iraq.

Thousands of civilians fled Mosul after ISIS's takeover of the city. The U.N. High Commissioner for Refugees released this video of residents fleeing. According to the United Nations, 500,000 Iraqis were displaced.

An image of a discarded Iraqi uniform was spotted outside Mosul.


In the city of Manbij, Syria, which has a strong ISIS presence, locals were seen celebrating Mosul's capture on the streets.

After Mosul, ISIS captured Tikrit and Baiji as the militant group moves toward Baghdad. The video is said to show thousands of Iraqi soldiers captured in Tikrit.

This video was posted on YouTube by a supporter of the insurgents. The burning vehicles were on a road between Tikrit and Kirkuk.

In Kirkuk, Kurdish militants took advantage of the disarray caused by ISIS and seized control of the region, reportedly without much of a fight.

An abandoned Iraqi police vehicle spotted outside Mosul on Thursday.
