British Prime Minister David Cameron has criticized Monday the use of the term "Islamic State" by the BBC when referring to Daesh.
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 attack.
At least 30 people out of the 38 killed at a popular resort in the Tunisian city of Sousse last Friday were British citizens, British media reports said Monday.
"What it is is an appalling barbarous regime that is a perversion of the religion of Islam and many Muslims will recoil every time they hear the words," said the British prime minister.
Cameron said "so-called" could be used or "ISIL" (for Islamic State of Iraq and the Levant).
In his remarks, stressing importance of fighting Daesh in every sense, Cameron said: "The fight against the barbaric terrorist organization [is] the struggle of our generation."
"We have to fight it with everything we can," said Cameron, adding that the strategy was to build local armies in fighting against the militants.
According to Tunisia’s interior minister, the attack on Friday was carried out by a student from the city of Kairouan, located roughly 60 kilometers west of Sousse.
The Daesh militant organization, which currently controls large swathes of Iraq and Syria, claimed responsibility for the attack, according to statements posted by the group on social media.
The deadly assault came roughly three months after 21 foreign tourists were gunned down by militants in a museum in the capital Tunis.
