McDonald's has apologised for a marketing slogan which read 'Sundae Bloody Sundae'.
Bloody Sunday is the term used to describe when British soldiers opened fire on peaceful activists in Northern Ireland on January 30, 1972.
A McDonald's restaurant in Portugal was spotted with a poster advertising a two-for-one promotion on ice creams, reports the Mirror Online.
However, a Twitter user appeared to take issue with the slogan employed, going on to tweet: 'Portugal is cancelled'.
The tweet, featuring a picture of the poster, went viral online - generating almost 5,000 likes.
In response to the backlash, a spokesperson for McDonald's Portugal issued a statement apologising for the gaffe.
The statement read: "When promoting its Halloween Sundae ice cream, McDonald’s Portugal developed a local market activation for a small number of its restaurants in Portugal.
"The campaign was intended as a celebration of Halloween, not as an insensitive reference to any historical event or to upset or insult anyone in any way.
"We sincerely apologise for any offence or distress this may have caused."
A total of 13 people died in Derry on Bloody Sunday , while one passed away a month later. A further fourteen were injured.
