Kabul, Afghanistan (CNN) -- A NATO airstrike targeted a police station in a remote district of Afghanistan's Nuristan province early Monday morning, killing at least four police officers and wounding eight others, officials said.
A provincial council head said the strike in Wama district was based on bad intelligence, but added that a NATO helicopter landed nearby and detained 12 police officers.
"This action will create distance among the government and people," Enaitullah Mazhabyar told CNN. "The people will not let their sons work as policemen anymore."
NATO is aware of the incident and is currently conducting an investigation to determine if the strike was a friendly-fire incident, said International Security Assistance Force spokesman Capt. Pietro D'Angelo.
In a separate incident, one ISAF service member died Monday following an insurgent attack in southern Afghanistan, NATO reported.
Monday marks the first day of the Islamic holy month of Ramadan.
