Hackers have claimed that a number of Islamic State supporters' social media accounts are being run from internet addresses linked to the Department of Work and Pensions.

A group of four young computer experts who call themselves VandaSec have unearthed evidence indicating that at least three ISIS-supporting accounts can be traced back to the DWP.

Every computer and mobile phone logs onto the internet using an IP address, which is a type of identification number.

The hacking collective showed Mirror Online details of the IP addresses used by a trio of separate digital jihadis to access Twitter accounts, which have been used to spread extremist propaganda.
