http://news.bbc.co.uk/1/hi/world/middle ... 198947.stmEight US marines have been charged over the deaths of 24 Iraqi civilians in the town of Haditha last year.
Four are accused of unpremeditated murder and four others are charged with attempting to cover up the incident.
Men, women and children were killed by marines who said they were under attack from insurgents at the time.
The US military initially said the civilians died in unrest. If found guilty of second-degree murder, the marines could face life imprisonment.
Squad leader Staff Sgt Frank Wuterich has been charged with the unpremeditated murder of 12 Iraqis and ordering his troops to kill six people, his lawyer Neal Puckett said.
Lance Cpl Justin Sharratt has also been charged with three such counts, his legal representatives say.
