Nato has confirmed that two rockets fired at militants during its offensive in Helmand, south Afghanistan, missed their target and killed 12 civilians.
The rockets struck a house in Marjah as thousands of Nato troops continued their operations to oust the Taliban.
Operation Moshtarak is the biggest Nato-led assault in Afghanistan since 2001 and the first big test of President Barack Obama's surge strategy for the country.
ABC's Miguel Marquez is with the US Marines in Marjah.
