ISIS claimed responsibility Thursday for the museum massacre in Tunisia and called the attack “a blessed invasion of one of the dens of infidels.”
In a message posted to an Internet forum known for supporting ISIS, the terror group warns that the bloodshed has only just begun, and labeled the two terrorists killed during Wednesday’s strike “knights of the Islamic State.”
The slain terrorists who took hostages in the Bardo Museum were identified Thursday as Tunisians who reportedly spent time in Iraq and Libya.
ISIS said the only reason the two died when authorities stormed the museum is that they ran out of bullets.
Following the massacre that claimed 23 innocent lives, authorities arrested nine people, including four being questioned about direct links to the attack and five others who had ties to a terror cell.
Two relatives of one of the killers were among those in custody.
Tunisia was still on edge after the terrorists went on their midday rampage in the capital of Tunis — gunning down tourists getting off buses and slaughtering hostages during a standoff with police.
Of the 23 people killed by terrorists, 20 were foreigners, said officials, who added that another 44 were wounded.
Among the victims was Sally Adey, 57, a mother of two and the only British citizen believed killed. Her husband, Robert, 52, is believed to have survived.
The day after the carnage, harrowing tales of survival emerged, including those of a woman who smeared blood over her body to “play dead” and two terrified tourists who stayed hidden inside the Bardo Museum overnight.
“We were all crammed together on top of each other and there were lots of wounded,” a French woman identified only as Maryline told France Info radio.
Two others who also escaped were Juan Carlos Sanchez and Cristina Rubio, Spanish tourists who survived after hiding out in the museum all night.
US officials said they are looking into ISIS’s claims that it was behind the massacre.
“This was not a lone-wolf attack,” said a source. “Unfortunately, they were the real thing, not amateurs.”
The source added: “I don’t think another attack in Tunisia is imminent. The authorities there are on high alert so they’ll lie low for a while.”
