Dozens of Aberdeen University staff have walked out in a strike over pay.

It follows two days of industrial action at universities in Glasgow and Edinburgh last week.

Staff have been offered a 1.1% pay increase by the Universities and Colleges Employers Association (UCEA).

Lecturers say they have suffered a 14.5% real-terms pay cut over the last six years.

Around a quarter of Scottish universities have been hit by industrial action as a result of the dispute.

The strike at Aberdeen University, which involved under 50 staff, is expected to be followed by similar action at the Robert Gordon University on Thursday.

Staff have also raised concerns about the use of zero-hours contracts by Scottish universities.

University and College Union official Mary Senior said: "The very last thing staff at Aberdeen University and Robert Gordon University want to do is go on strike but they have been left no other option.

"Universities have created a dispute when this could all have been avoided if they made a reasonable pay offer."

A spokesman for Aberdeen University said: "As expected, only a small percentage of staff have participated in the national strike action today.

"The university term has ended and the institution continued to operate as normal."
