HUNDREDS of horrific images of the Morocco beheading have been sent directly to the victim's MUM by sick ISIS supporters.

Uncensored images of the severed and partially severed heads of one of two backpackers to be murdered in the Moroccan mountains have been plastered all over the Facebook page of one of their grieving mothers.

It is not clear if the images were taken by investigators or the killers. The horror development came after friends urged people not to watch a video showing the decapitation of one of the victims.

The bodies of Louisa Vesterager Jespersen, 24, from Denmark, and Maren Ueland, 28, of Norway, were discovered by French hikers on Monday morning.

Friends of Ms Ueland’s mother Irene, who was bombarded with the sick images, have urged people to stop watching the video.

Vanessa Bailey wrote on Twitter: "Please don't watch the #Morocco video. You know what's going to be on it, you know what you'll see. Someone's precious daughters in their final moments, horrifically robbed of their lives. Don't give the monsters the satisfaction. You can give these beautiful girls their dignity".

Some of the images sent to the mum appear to have been posted by local Moroccans in a bizarre attempt to express condolences, with the distressing images captioned with calls for the killers to be put to death.

It was earlier suggested that the killers sent the gruesome video directly to the friends of the victims online.

New York Times correspondent Rukmini Callimachi tweeted: "A European official close to the investigation confirmed that the beheading video was sent by private messenger to friends of the killed Danish woman by unknown senders who appeared to have Moroccan profiles. Police is investigating."

The footage circulating on social media shows a woman who appears to be Ms Jesperson screaming while a man cuts her neck with what appears to be a kitchen knife.

During the video, the perpetrators cry out: "It's Allah's will" and are heard saying: "This is revenge for our brothers in Hajine in Syria. These are your heads, enemy of God", referencing an ISIS stronghold seized by US-backed forces this week.

Yesterday, a separate clip on Twitter appeared to show the four men suspected of murdering the tourists pledging their alliance to ISIS leader Abu Bakr al-Baghdadi.

One of them holds a knife as they sit in front of a black and white flag.

The second video has been verified by intelligence analysts but authorities are yet to comment on the footage.

Danish and Norwegian authorities have now both confirmed that the first video showing a beheading was genuine.

But a police source later told the Reuters news agency that it appeared to have been filmed in a different place from where the bodies were found.

Police arrested three suspects on Thursday as they tried to flee on a bus while hiding massive knives and slingshots under their seats.

And on Friday they made a further nine arrests, despite previous claims that they were not looking for any further suspects.

A national security official has identified three of the suspects to the Associated Press as Abdessamad Ejjoud, born in 1993, Younes Ouziad, born in 1991, and Rashid Aftati, born in 1986.

The brother of prime suspect Younes has described him as "illiterate" and an "enthusiastic hunter" who "refused to get a job".

He is thought to be the first to be arrested after he fled, leaving his identity card at the scene.

The brother, who declined to give his name and was pictured only from behind, told how his brother was brainwashed by extremists.

"My brother was just a young guy like all the others. Then he grew a beard and became religious," he told the Mail Online.

"The first thing you have to know is that he is illiterate. That means it is easy for criminals to influence him to do whatever they want."

He added that his brother seemed "normal" in the days before killing, saying: "Only God knows who influenced him. The police have to control those cells. They have to control them throughout the country because they are brainwashing our brothers and children."

Prior to their hike, Maren and Louisa stayed for a week in a cheap hotel in the heart of Marrakech, vg.no reports - raising concerns that they were followed by their killers from the city.

CCTV footage showed them setting up camp 600 yards from where the women were sleeping - and later leaving the area at 3am on Monday morning.

A source told Morocco World News: “The suspects were camping in the same area that the murder took place.

"Witnesses saw the group at night as they were heading to the camp area.”

Louisa's ex-boyfriend paid tribute to the Danish student in a heartfelt Facebook post, writing: "Dear amazing Lulu, funny, full of energy, bundle of joy, inclusive, caring and thoughtful.

"No idea how many times we were on a trip together and I turn around and you were disappeared, because so to find you far behind me because you had to look closer to a beautiful flower, view or something that the average person wouldn't notice even. You saw beauty in every smallest detail."

He added that the couple had parted this summer but remained "best friends".

He added: "You travelled around the world just as you would, you would not be limited by fear of all the dangers of the world. You did what you wanted and you were tough."

Both women were studying outdoor activities and cultural guidance at the University of Southeastern Norway and attended a campus in Boe, west of Oslo.

Their bodies were found by their tent in an isolated spot two hours walk from the village of Imlil, where hikers often start walks to Mount Toubkal in the Atlas mountains.

AFP reported that the bodies of the women were being flown back to Copenhagen from Morocco on Friday.

Compared to other countries in North Africa, Morocco has been largely insulated from militant attacks.

The most recent took place in April 2011, when around 17 people were killed in a bombing of a restaurant in Marrakech.
