Kildare Now news website has apologised for an "offensive" April Fool story claiming Isis had annexed a Kildare landmark.
Social media users have slated the website after their story was posted this morning on April Fools' Day.
In it they wrote that "Irish security forces have placed a ring of steel around the Allen area and road diversions are in place until further notice after a male calling himself Paddy Jihaddy said he had rigged the area with explosives and that he was renaming the locality the Hill of Allah.
“A spokesperson for the Defence Forces has issued a statement saying that they hope to have the situation resolved by 12 noon when normal life can resume once more.”
The website posted a picture of a local landmark with an ISIS flag photoshopped on top of the building.
The reaction to the story on Twitter was swift and damning.
The Irish news website has now apologised and said it was "completely unauthorised and was not posted by a member of the editorial team".
Kildare Now said in a statement: "An article and photograph was posted on KildareNow this morning purporting to be an April Fools Day-type story.
"KildareNow would like to point out that the story was completely unauthorised and was not posted by a member of the editorial team.
"The article and photograph have both been removed from the KildareNow website and our Facebook account.
Oh, my sides. Hilarious. Ho Ho Ho. Make it stop. Seriously. https://t.co/7UDaqxHhqi— Jason O'Brien (@jasonpobrien) April 1, 2016
"KildareNow would like to apologise unreservedly to everybody who was rightly offended by the article which was extremely insensitive especially in light of recent tragic events in Brussels and elsewhere.
"A full internal investigation is now underway into how the KildareNow site was accessed in this way."
The story and the social media links have now been removed.
