As of right now:
MSNBC wrote:KABUL, Afghanistan - U.S. forces mistakenly killed seven Afghan police and wounded four in an apparent friendly fire incident early Tuesday in eastern Afghanistan, Afghan officials said.
Police manning a remote checkpoint in Nangarhar province said an American convoy backed by helicopters approached and opened fire despite their protests and calls for them to stop.
“I thought they were Taliban, and we shouted at them to stop, but they came closer and they opened fire,” said Khan Mohammad, one of the policemen at the post. “I’m very angry. We are here to protect the Afghan government and help serve the Afghan government, but the Americans have come to kill us.”

There were conflicting reports over how the fighting started.

CNN wrote:KABUL, Afghanistan (AP) -- Mistaking each other for the enemy, Afghan police fired 49 rocket-propelled grenades at U.S.-led coalition troops on an early morning mission Tuesday, prompting the Americans to fire back and call in helicopter gunships, killing eight police, officials said.
The deadly lapse in communication underscores the wide gaps -- and apparent mistrust -- between U.S. and Afghan security forces. President Hamid Karzai's office labeled the deaths "a tragic incident" caused by a lack of cooperation and communication.

"The police forces were not aware of the coalition's operation," said Rahimi. "The police checkpoint in the area thought that they were the enemy, so police opened fire on the coalition, and then the coalition thought that the enemies were firing on them, so they returned fire back."

"We are here to protect the Afghan government and help serve the Afghan government, but the Americans have come to kill us," said Khan Mohammad, one of the policemen at the post, who said the police thought they were under attack by the Taliban.

Fox wrote:KABUL, Afghanistan — Afghan police mistook U.S. troops on a nighttime mission for Taliban fighters and opened fire on them, prompting U.S. forces to return fire and call in attack aircraft, killing seven Afghan police, officials said Tuesday.
Gunmen on motorbikes, meanwhile, killed two schoolgirls Tuesday in central Afghanistan, as U.S.-led coalition and Afghan troops killed more than 24 suspected Taliban fighters during a battle in the south on Monday, officials said.

The CNN and Fox articles are nearly identical, except the Fox article's second paragraph is a seemingly unrelated blurb about two schoolgirls being killed by gunmen on motorcycles before going into the friendly fire story.
All three articles contain the same quote from Khan Muhammad claiming “I’m very angry. We are here to protect the Afghan government and help serve the Afghan government, but the Americans have come to kill us,” but MSNBC has the quote in the beginning of the article as opposed to the other two.
However, after reading all three articles, I'd conclude that they're all pretty much saying the same thing and that the CNN article is probably the most, at first reading, objective.
The biggest difference is that MSNBC starts the article from the perspective of the police on patrol and then goes into the conflicting reports. CNN starts with a lapse-in communication between US and Afghan forces and then Fox pretty much says the same thing only it starts with the blurb about the gunmen on motorbikes and goes into what Karzai's spokesman said.
