Royal Mail has said it is facing severe disruption to its international export services after a “cyber incident”.
“We are temporarily unable to despatch items to overseas destinations,” it said.
“Some customers may experience delay or disruption to items already shipped for export.
“Our import operations continue to perform a full service with some minor delays.”
The firm is temporarily advising customers to hold any export mail while it attempts to resolve the issue
Royal Mail added that it had launched an investigation into the incident, was “working with external experts” and “sincerely apologised” to customers for the disruption.
Their import services remain operational, but are experiencing minor delays.
The incident comes at a difficult time for Royal Mail, which is currently embroiled in a bitter row over jobs, pay and conditions with the Communication Workers Union that resulted in a series of strikes last year.
