The corpses of 49 soldiers of Iraq's new army have been found north of the capital Baghdad.
Police and Iraqi National Guard officers said 37 bodies had been recovered on Saturday from the vicinity of Baquba and another 12 on Sunday morning.
General Walid al-Azzawi, commander of the Diyala provincial police, said the bodies had been laid out in rows.
"After inspection, we found out that they were shot after being ordered to lay down on the earth," he said.
Al-Azzawi said they were all members of the new Iraqi army and were training in Kirkush military camp in Baladruz.
He said they were probably returning home for leave since many were from the southern provinces. An investigation is underway, al-Azzawi added.
**Samarra clashes***
In Samarra, a 17-year-old girl and an 11-year-old Iraqi boy were killed and four people wounded in clashes between US troops and armed fighters, police said on Sunday.
Police said the two were killed on the northern outskirts of the city, 100km from the Iraqi capital, in the fighting on Saturday evening.
Witnesses said a US military Humvee vehicle also damaged.
A US military spokeswoman had no immediate comment.
US troops and Iraqi National Guards have maintained a strong presence in most parts of the Sunni Muslim city since an assault early this month that resulted in the deaths and detention of several armed fighters.
The Iraqi government said Samarra had been pacified in that assault, part of a plan to retake all "rebel" areas by political or military means before elections planned for January.
But residents say US troops and armed fighters skirmish daily in the city, which remains under curfew at night.
**Abu Ghraib blast***
Aljazeera has also learned that a car bomb exploded near a US patrol near a governmental compound in the Abu Ghraib area of Baghdad.
The explosion has caused casualties among the soldiers and damaged some vehicles. No further details are available.
Elsewhere, an explosive device detonated on the Kharnabat bridge in western Baghdad, destroying a tank that later fell into the river.
US forces have sealed off the site.
