The BBC was feared to have fallen victim to an ISIS cyber-attack this evening as 'hackers' appeared to post Islamic State propaganda during a live broadcast.

Viewers were left stunned as the words 'Je suIS IS' appeared on TV screens following a feature on the BBC News Channel.

 Above the red and white writing was the word 'CYBERCALIPHATE'.

 Newsreader Clive Myrie was clearly flustered as he addressed the loss of content during the programme.

 He said: "I do apologise, we seem to have lost our report from James Robbins, erm... stay with us."

The incident happened just after 8.07pm leaving producers scrambling to the next feature.

 The incident follows today's hacking of the television network TV5Monde.

Unlike the French attack, the BBC have stated that it was an 'operational error' that lead to the loss of sound and confusion.

A BBC spokesperson told Mirror Online: "This was an operational error in which a graphic being used in BBC reports about the French cyber-attack was broadcast briefly by mistake during another item."
