A soldier being reunited with his mum after two years apart has driven home the personal mission of Iraqi fighters battling to retake Mosul from Islamic State.
Footage released by the BBC on Tuesday shows an Iraqi soldier being reunited with his mum near Mosul, where an alliance of Iraqi forces backed by US airstrikes have battled for almost a month to reclaim Islamic State's last bastion in Iraq.
The terror group captured the city -- which is home to nearly 1.5 million people -- in 2014.
In the video a young Iraqi soldier named Saad -- who has not been to Mosul, or seen his family, in two years -- finds his mum on a bus filled with civilians fleeing the city.
"Don't cry my son. You shouldn't cry," says his mum as she hugs him through the emotional reunion.

"My darling I'd die for you."
More than 9000 families have been displaced from the Iraqi city of Mosul as the campaign to reclaim it from ISIS enters its fifth week.
More than 54,000 people had been internally displaced amid military operations to retake Mosul in Iraq, an increase of 6,600 people since November 11, the United Nations said on Tuesday.
A 100,000 strong alliance of Iraqi forces have surrounded the city, which is a critical last major post for ISIS in Iraq and is now the site of the biggest military operation in the country since the 2003 U.S. lead invasion in 2003.
The UN said about three quarters of the displaced families are sheltered in camps and one quarter in host communities, while available spaces in formal camps are still keeping pace with displacements.
The World Food Programme (WFP) is providing food assistance to more than 100,000 people fleeing the conflict in Mosul, including a distribution on Sunday to 25,000 people in Gogjali, the first neighbourhood retaken inside Mosul City.
Kurdish peshmerga and Shi'ite fighters have been making painfully slow progress towards the city from the east, south and north of the city.
During last week's push, Iraqi forces discovered a mass grave containing 100 decapitated bodies.
