“It is tragic news that six of our soldiers are missing, presumed dead, in Afghanistan. Our hearts go out to their families, friends and colleagues.
“This is a dark day.
“We salute all of our fallen and those who continue to serve in the face of the gravest danger. They are serving with bravery and courage and we owe them all a huge debt of gratitude.”
Jim Murphy MP, Shadow Defence Secretary, said:
“This is a terrible tragedy which will bring profound loss to six families and real hurt to the whole country.
“The professionalism of UK service personnel is unmatched and their bravery is unending.
“This tragedy underlines the daily dangers our Forces face and the importance of their role in stabilising a nation that can never again become an incubator for terrorism.
“In our sadness it is still important to remember that this painful mission is in our country’s national interest.”
