BAGHDAD - An American soldier died in a non- combat incident in northern Iraq, bringing the death toll of US troops in the country to six so far this month, the US military said on Monday.

The soldier died on Friday due to what a US military statement called non-hostile incident, referring to that the soldier was not killed due to combat operations.

The brief military statement did not give further details about how and where exactly the incident occurred.

The name of the deceased is being withheld pending notification of next of kin, the statement said.

The latest death is the sixth so far in April, only two of them were killed by insurgents' indirect fire (rocket or mortar fire), according to military statements.

The death toll of US soldiers, who have been killed in Iraq since the war broke out in 2003, rose to about 4,447, according to media count based on Pentagon figures.

In mid 2010, US troops in Iraq had been reduced to below 50, 000 soldiers. Washington said that the remaining US troops in Iraq are conducting support and training missions.

US military forces are to pull out completely from Iraq by the end of 2011 according to the Status of Forces Agreement, the security pact signed late in 2008 between Baghdad and Washington.
