A Fife optician kidnapped by Nigerian militants has been freed with two others.

Alanna Carson survived the ordeal, while Ian Squire was killed before the group's release was negotiated.

They were kidnapped by gunmen in Burutu on October 13 along with Cambridge GPs David and Shirley Donovan.

The group are believed to have been in Nigeria working with Christian medical charity New Foundations.

Ms Carson is from Northern Ireland but worked at Specsavers in Leven, Fife.

Store director Adrian McCann said: "We are hugely relieved to hear that our colleague has been safely released and back home with her family."

In a statement released on Monday, the families of the kidnap victims described the past three weeks as "traumatic".

"We are delighted and relieved that Alanna, David and Shirley have returned home safely," they said.

"Our thoughts are now with the family and friends of Ian as we come to terms with his sad death.

"This has been a traumatic time for our loved ones who were kidnapped and for their families and friends here in the UK."
