Devising new ways to indoctrinate the next generation of jihadis, Islamic State (ISIS/ISIL) is providing apps to teach children how to attack landmarks in the West, reported The Independent.

The apps are distributed through kiosks set up in territory controlled by the brutal terror group where children can read the latest issues of ISIS’ online magazine Rumiyah (a simpler version of their magazine Dabiq) and learn Arabic.

“[The app] is supposed to teach them Arabic. But the words they learn are related to violence and extremism such as tanks and grenades. The children are rewarded if they say they are prepared to carry out attacks on the West, the targets are places like the Statue of Liberty, Big Ben and the Eiffel Tower,” said Colonel John Dorrian, who is with the U.S.-led coalition against ISIS.

“We are obviously very concerned about what they are learning through these apps turning to reality. But at the same time we need to take care of these children when the time comes, untold damage has been done to them which needs to be undone,” Dorrian added.

Children brainwashed by ISIS, dubbed by the group the “Caliphate Cubs,” are estimated at 1,500. The majority of the children are from Syria and Iraq and other Arabic-speaking countries. However, an estimated 50 are from the UK, with lesser numbers from France, Australia and other Western countries.

“We need to consider what needs to be done with these children. Some of them who have been used to carry out criminal acts, some really dreadful ones, are below the age of criminal responsibility in many countries in Europe. We know of children from the West who have been taken to Syria, but there are also children who have been born there to European parents. This is a complicated scenario and there are no easy answers,” said a senior British official quoted in The Independent
