Islamic State (Isis) Telegram channels are calling on supporters in Europe to rush along with their plan of attacks, while also cautioning them to delete all IS (Daesh) related content from their phones and other devices. A new message posted by a pro-IS group called the Nashir Foundation, was circulated on the encrypted messaging app in English, French and Arabic.

The message called on "our brothers in Europe, specifically in France" to hurry up and execute their operations while also warning them "to take care and to be cautious", Voactiv reported. The message was allegedly broadcast late on 3 September.

"We've received reports... that many brothers (were) arrested before their operations," the message reads. "So, we advise you to delete anything related to the Islamic state from your devices, such as photos, videos and apps. And we advise you to hurry in your operations before it becomes too late."

The message comes on the heels of the recent death of Syrian-born IS commander Abu Muhammad al-Adnani, who was reportedly killed in or around Aleppo, an area rife with violence and which has been under siege since the Syrian conflict first began. The US and Russia have both claimed they were independently responsible for bringing down one of the key figures of the extremist group.

The terror group has since vowed to avenge al-Adnani's death, warning that a new wave of emerging IS supporters that "loves death more than life" will "stay determined to seek revenge".

A deadly series of IS-inspired recent lone-wolf attacks across the globe, including the Orlando shooting, the Nice attacks and the Normandy attacks have rocked the world. On 1 September, the extremist group also claimed responsibility for yet another attack that saw two policemen and a bystander injured in a shooting in Copenhagen. The attack, claimed by the IS-linked Amaq News Agency, marks the first time the terror group has claimed responsibility for an attack in Denmark.
