McDonald's in Portugal has issued an apology after customers slammed the company's Halloween promotion which used the slogan "Sundae Bloody Sundae".
The two-for-one offer on strawberry sundaes did not go down well with customers.
While the company says it was intended to be a reference to U2's song "Sunday Bloody Sunday", customers slammed it as historically insensitive.
The campaign was pulled after numerous complaints and the company issued an apology.
