The British Prime Minister, Mr. David Cameron has said that the U.K troops killed in Afghanistan did not die in vain. As a four-year mission in Sangin ended, he said the British troops had performed magnificently in the area of Helmand province which had seen the U.K's heaviest losses. He said out of the 337 U.K deaths since 2001, one third have happened in Sangin. The United Kingdom has handed responsibility for security there to U.S forces with 1,000 Royal Marines and other personnel redeployed to central Helmand province. Mr. Cameron said these decisions are never easy but this is the right decision. We should share the burden properly with our allies, we should concentrate our forces where they can have the maximum impact.
