The Islamic State (ISIS) terrorist group beheaded a four-year-old girl in Syria after she refused to obey her mother's wish for her to go home, according to a report.

After the beheading, the ISIS ordered the mother to soak her hands in her daughter's blood.

A Syrian woman who escaped from Raqqa in Syria told the story.

"A mother told her four-year daughter to go home and she refused and then the mother told her unintentionally 'go home and I swear to God that I will behead you if you don't,' and one of the ISIS members heard this and told the mother since you swore to God you should behead her but the mother strongly opposed," the woman told Alalam news channel.

She added, "But they beheaded the little girl and soaked her mother's hands in her daughter's blood."

The woman who requested that her name be withheld said the ISIS has filled the Tal Abyaz street to al-Naeem square in Raqqa with heads of slaughtered people to instil fear in the community. The militants also displayed the mutilated body of a young man who refused to join ISIS and hung his head.

The witness also said ISIS members "rape women, take children to war, loot houses and threaten people in Raqqa with beheadings if they don't agree with their daughters' marriage with the ISIS members."

Last year, ISIS fed a mom the mutilated remains of her son after she was told it was cooked meat and rice, the Mirror newspaper reported.

The son was captured and became an ISIS prisoner in Mosul, Iraq. The mother went to ISIS' headquarters to talk to her son.

ISIS told her to eat first because of her long trip but was told afterwards that her meal was her son.

The terrorist group has been perpetuating atrocities against everyone including children and mothers.

A June 2015 report by the Syrian Observatory for Human Rights said ISIS had executed 3,000 people in the past year including 74 children.
