"We cordoned off their property and arrested three people who earlier fired their weapons. They are Nepalese," said military spokesman Major General Qassim Atta, adding that the guards were partying at the time. [break]
The three men were guarding "an American communications company" based inside the Green Zone, a sprawling, well-guarded complex where many Iraqi leaders, foreign diplomats and businesses are based, according to Atta.
No one was wounded in the incident, he said.
Two security contractors, one British and the other Australian, were killed in an alcohol-fueled shooting inside the Green Zone in August last year.
British security guard Danny Fitzsimons is to stand trial for the killings.
