British Prime Minister David Cameron criticized Monday the use of the term "Islamic State" by the BBC when referring to the so-called 'Islamic State of Iraq and the Levant' (ISIL) takfiri group.

Speaking to BBC Radio 4, Cameron said he preferred the terms "so-called" or "ISIL".

"I wish the BBC would stop calling it 'Islamic State' because it is not an Islamic state," said Cameron in an interview, three days after the Tunisia beach attack that killed 30 British tourists.

"What it is is an appalling barbarous regime that is a perversion of the religion of Islam," said the British prime minister.

In his remarks, Cameron said "the fight against the barbaric terrorist organization is the struggle of our generation," stressing importance of fighting ISIL in every sense.

"We have to fight it with everything we can," said Cameron, adding that the strategy was to build local armies in fighting against the armed group.

At least 30 Britons are believed to have been killed in the beach massacre in Tunisia as informed sources said the eventual figure could be even higher.
