The rock band was scheduled to play Glasgow's OVO Hydro on Friday and Saturday before moving to Belfast's SSE Arena and Dublin's 3 Arena next week.

But on Friday morning, the band posted on social media, writing: "Due to an urgent family matter, Travis has had to return home to the States.

"The Glasgow, Belfast, and Dublin shows are being postponed.

"More information in regards to his return to Europe and rescheduled dates will be provided as soon as available."

Barker, 47, also shared photos from what appeared to be an airport prayer room to his Instagram story.

The musician and his wife Kourtney Kardashian, 44, are currently expecting their first child together.

In June, the reality star posted an Instagram video showing her holding up a sign at a Blink-182 concert saying: "Travis I'm pregnant."

The couple announced in May last year that they were legally married after holding a "practice" wedding after the Grammys in April hosted by an Elvis Presley impersonator at 2am.

Barker has been married twice previously, first briefly to Melissa Kennedy and then to actress and former Miss USA Shanna Moakler, with whom he has two children.

Kardashian also has three children with US media personality Scott Disick, with whom she was in an on-off relationship for almost 10 years.
