As Operation Moshtarak in Afghanistan's Helmand province enters its seventh day, concern is growing over civilians trapped in Marjah city.

Hundreds wounded in the fighting have flocked to the only hospital providing international standard healthcare to civilians.

The assault on the Taliban stronghold of Marjah is the first major test of US President Barack Obama's strategy to crush an eight-year opposition campaign. The joint operation by international troops and Afghan forces is also one of the biggest since the 2001 US-led invasion brought down the Taliban regime.
