US forces in Iraq have killed two women in an air attack on a house in Baquba, a day after five girls were killed by US tank fire in Ramadi.
The US military said American soldiers engaged in a gun battle in the northern city called in air support that killed eight suspected insurgents.
The military said the soldiers searching the building also found the bodies of two women.
Iraqi police said all the dead were civilians from two families.
Police said they were a man and his three sons and another couple and their son and daughter.
The US military statement said: "Due to the heavy volume of enemy fire, Coalition forces also engaged the terrorists with aircraft. Coalition aircraft fired rounds neutralising the enemy threat."
Baquba lies about 60km (35 miles) northeast of Baghdad and has been scene of some of the worst violence and instability in Iraq since the US-led invasion in 2003.
US President George W Bush is preparing to meet Iraq's Prime Minister Nouri Maliki in Jordan amid a rising tide of sectarian and anti-US violence.
In other incidents on Wednesday, a bomb exploded next to a bus station in the al-Nahda area of Baghdad, killing two people.
North of the capital a suicide car bomber rammed into a police station, as dozens of gunmen attacked a nearby checkpoint, Iraqi security officials said.
Six people were reportedly killed and the nearby city of Samarra was put under indefinite curfew.
On Tuesday, a man and five girls were killed in Ramadi, in western Iraq, when coalition forces fired tank gun rounds into a building during a fight with insurgents.
The US military also announced that two American soldiers died from their injuries in separate incidents in Iraq on Tuesday.
