LONDON (AFP) - The BBC sparked a social media storm after screening a comedy sketch called "The Real Housewives of ISIS", satirising the women lured into joining the Islamic State in Iraq and Syria (ISIS) militant group.

The two-minute sketch, which featured in the comedy show "Revolting", has been seen more than 21 million times and drawn nearly 90,000 comments on the BBC 2 television channel's Facebook page since airing on Tuesday (Jan 3).

The reaction has varied between those who found it "sick" and "tasteless", causing "pain and hurt", to others who found it "hilarious", and lauded it for mocking the "violent, paedophilic, regressive death cult" of ISIS.

"The Real Housewives" US reality television franchise shows the lives of affluent women in various cities.

In the "Revolting" sketch, they are replaced by black-clad British wives of ISIS militants who discuss their outfits, including two women turning up in matching suicide vests.

"It's only three days till the beheading, and I've got no idea what I'm going to wear," complains one.

"Ali bought me a new chain which is eight foot long, so I can almost get outside, which is great!" says another, attached to an oven.

While the BBC declined to comment, Jolyon Rubinstein, one of the duo behind "Revolting", which satirises current affairs, posted on Twitter: "Why shouldn't we mock female jihadists?" His co-creator Heydon Prowse said he was "glad the nation (is) discussing this".

Both retweeted the comments of Ali Official, a British comedian of Bangladeshi descent, who said: "The sketch ridicules online grooming and draws attention to an important topic. The whole point of satire is to expose stupidity.

"Satire like this highlights the absurdity of those that recruit and get recruited for ISIS."
