[Prime Minister] David Cameron said: 'It was an extraordinarily brave, breathtaking operation that our troops had to carry out. I pay tribute to their skill and dedication.'
Speaking outside No 10 Downing Street, the Prime Minister said the rescue should serve as a warning to terrorists across the world who targeted British citizens.
'They should know if they take British citizens as hostage we do not pay ransoms, we do not trade prisoners. They can expect a swift and brutal end.'
