A Thai man filmed himself killing his baby daughter on Facebook Live, before taking his own life, Thai police say.
The 21-year-old hanged his daughter, and then himself, at a deserted hotel in Phuket on Monday, reportedly after an argument with his wife.
Facebook sent condolences to the family for the “appalling” incident and said that the content had now been removed.
The company pledged a review of its processes after footage of a US killing stayed online for hours this month.
Relatives of the Thai man saw the distressing footage and alerted the police – but the authorities arrived too late to save the man and his daughter.
The footage shows the man tying a knot around his daughter’s neck, before dropping her from a rooftop. He then retrieves the body.
Social media anger
The Facebook Live post was widely reported by Thai media, and went viral on social media, BBC Thai editor Nopporn Wong-Anan reports.
The video is still live on video sharing website YouTube. The company has not yet commented.
Thai social media users reacted with anger, while offering condolences to the family of the girl, our correspondent says.
Devastated relatives of the child, including the mother, picked up the body of the girl and her father from hospital on Tuesday.
Following the US killing, Facebook said it was “constantly exploring ways that new technologies can help us make sure Facebook is a safe environment”.
“We prioritise reports with serious safety implications for our community, and are working on making that review process go even faster,” blogged one of its executives last week.
