Virginia: Three Virginia police officers were shot – one of them fatally on her first day on the job – after they responded to a domestic incident in the US state of Virginia.

Officer Ashley Guindon died Saturday and the two other unidentified officers were wounded after responding to the call in the Woodbridge-Lake Ridge area south of the Prince William County government administration centre.

"When they got to the door, the suspect started shooting," Prince William County Commonwealth's Attorney Paul Ebert said.

The Prince William County jail later identified the suspect as Ronald Hamilton, an active-duty Army staff sergeant based at the Pentagon.
