Scottish workers held in Nigeria freed

From the BBC:

Scottish oil workers held hostage for nearly three weeks in Nigeria have said they feared being "sacrificed".
Graeme Buchan, Paul Smith, George McLean and Sandy Cruden had been seized by armed militants.
Mr Buchan said he was even forced at gunpoint to tell his employers Mr Smith was dead.
Mr Buchan, speaking at Aberdeen Airport, said: "The gun at my head may have uncovered a talent for acting I did not know I had."
Mr Buchan, alongside Mr Cruden and Mr Smith, who work for Sparrows Offshore in Aberdeen, touched down in Aberdeen Airport on Monday morning.
