Iraq is facing its worst crisis since the US-led invasion of 2003, as sectarian tensions simmer and violence worsens.
The sectarian strife and violence are being felt most acutely by the Yazidi minority, who have faced an attack on their homes by Sunni militants in northern Iraq.
More than 50,000 Yazidis fled the area following an attack by Sunni fighters, who also took control of the town of Sinjar, 40km (25 miles) south of the capital Baghdad.
The United Nations says more than 8,000 people have been killed since the conflict erupted in 2014.
The attacks on Sinjar and other towns in Iraq have prompted the US to halt all military and diplomatic missions to the country.US President Donald Trump’s administration says it has halted a number of diplomatic missions in Iraq, but it is unclear how many others have been affected.
Iraqi Prime Minister Haider al-Abadi has accused Iran of funding the Sunni militants, who were allied with the US, and said Iran was not interested in peace talks with the Iraqi government.
The US has already said it will send more than 300 US military advisers to Iraq to train local troops and to train Kurdish fighters.
The Iraqi government has also announced a plan to send more US forces to help rebuild Sinjar.
However, Iraqi government forces have been unable to hold the area and there have been reports of a mass exodus of Yazidis.
The crisis began after the US removed the last US troops in Iraq after the withdrawal of the last American troops in 2015.US officials say that while there is a need for a political solution, there are no guarantees that the US will be able to maintain security in the region.
