On June 10, an Afghan army commando killed three US soldiers and wounded another.
One or possibly two attackers were still alive and fighting with police, he said.
Since launching their spring offensive in April, the Taliban have been attacking Afghan army and police bases, killing several dozen men in recent weeks.
The news comes as President Donald Trump recently gave Secretary of Defense James Mattis the authority to establish troop levels and as concerns have come from "the top USA commander in Afghanistan that he doesn't have enough forces to help Afghanistan's army against a resurgent Taliban insurgency", according to the Post.
Taliban spokesman Zabihullah Mujahid claimed responsibility for the operation in a statement.
An Afghan Army spokesman on June 17 said the rogue soldier was killed in an ensuing shoot-out, the second so-called insider attack on USA forces in the past week. In March another insider attack killed three USA soldiers. Local journalists say the attack is not over as yet.
Gen. Dawlat Waziri, spokesman for the Afghan Defense Ministry, also confirmed the attack.
But last week, in an equally dramatic response, hundreds of Islamic State fighters captured Tora Bora, the underground labyrinth that was once the redoubt of al-Qaida leader Osama bin Laden.
Civilians as well as officers were wounded both in the gun battle and the auto bomb's blast, Danesh said.
Since peaking at a force of about 100,000 troops, some 8,400 USA service members remain in Afghanistan after most North Atlantic Treaty Organisation forces pulled out in 2014. The so-called green-on-blue attacks have been a recurring problem for the American training mission in the country.
The Pentagon is set to announce it is sending another 4,000 USA troops to the country to counter the insurgents.
Nevertheless, these attacks fueled a strong sense of mistrust between the coalition soldiers and the Afghan military.
