About 70% of Iraqis believe security has deteriorated in the area covered by the US military "surge" of the past six months, an opinion poll suggests.
The survey by the BBC, ABC News and NHK of more than 2,000 people across Iraq also suggests that nearly 60% see attacks on US-led forces as justified.
This rises to 93% among Sunni Muslims compared to 50% for Shia.
