LONDON - British Prime Minister David Cameron hailed the death of Osama bin Laden as a massive step forward in the fight against terrorism. In a statement, the prime minister said: The news that Osama is dead will bring great relief to people across the world. Osama bin Laden was responsible for the worst terrorist atrocities the world has seen - for 9/11 and for so many attacks, which have cost thousands of lives, many of them British. It is a great success that he has been found and will no longer be able to pursue his campaign of global terror.
