There has been a mixed reaction from Sangin residents to the transfer of security from British to American forces in the Helmand district. The handover to US Marines marks the end of the British mission in Sangin, after four years and more than 100 UK lives lost. ''It makes no difference," said Sangin resident Wali Shah. "They are both the two ears of the same horse. They don't care about us because they are more concerned about securing their own interests." British forces fought a bitter counter-insurgency campaign against the Taliban in Sangin.But Abdul Manan, a shopkeeper in the dusty market town of Sangin, which shares the name of the wider district, did not think the UK mission had changed much for the better. ''British troops didn't have any major success or a significant achievement," he said. "They came and made big promises but brought violence and displaced a lot of people.'' Sangin - situated around 100km (62 miles) north-east of the provincial capital, Lashkar Gah - is a hotspot for insurgent violence and opium production. "The security situation was much better before the arrival of British forces," said Khairullah, a local farmer. "We couldn't go to work. We hope that it will get better soon."
