Major Afghan Offensive 'Under Way in Marjah'

US military officials say thousands of Nato-led troops in Afghanistan have launched the biggest offensive since the overthrow of the Taliban in 2001. The operation, in the Marjah area, involves US, British and Afghan forces, supported by Danes and Estonians. Nato says Marjah is home to the biggest community under insurgent control in southern Afghanistan. Many residents fled ahead of Operation Moshtarak, which means "together" in the Dari language.
