The operation was in rugged Nangarhar province, where Osama bin Laden once had a base in the Tora Bora cave network and which has been the focus of air strikes in recent months.
Since the Peshawar attack in December, Afghan forces have stepped up operations against a division of Tehreek-e-Taliban Pakistan, which claimed responsibility for the school killings and has bases in Afghanistan.
Azrat Hussain Mashriqiwal, a spokesperson for Nangarhar's police chief, said 26 militants were injured and four captured, including three Pakistani citizens in the fighting that ended on Wednesday.
One Afghan policeman was killed.
During the operation Afghan forces seized a cache of weapons and explosives from the insurgents, Mashriqiwal said.
"If we notice any insurgent activity in any district of Nangarhar, we are ready to launch operations against them," Mashriqiwal said.
The fighting was in Nazyan district, which borders Pakistan's tribal areas near Peshawar.
The Afghan Taliban on Wednesday said they had shot down a US Chinook helicopter, killing and wounding dozens of Afghan troops in Nazyan district during "an offensive by the puppet forces".
The report was denied by US military officials.

And what will Pakistan going to do against the Quetta Shura and Haqqani? At what point do you show shame?
@Asfandyar: That would be "eyelashes" not eyelids. Besides, no, we are not unhappy that you are dismantling the terror network. We couldn't be happier.
@Asfandyar: @Ammar: It was Imran Khan who wanted to open offices for them and they appointed Imran Khan to represent them in the negotiations with Pakistan and it was all political parties of Pakistan that passed several unanimous resolutions saying that they are good muslims who have been just misled and wanted them to discuss on the changes to Pakistan's constitution.
Lal Masjid cleric is in Islamabad and challenging the army, law enforcement agencies and the courts but no one has courage to implement the court's judgement to arrest him.
Keep blaming India !!!!!!!!
Afghanistan and Pakistan are facing the impact of terrorism on both sides of the border. It is in the best interests of both nations to work together and combine their strength against the common threat of terrorism in the region.
