No group immediately claimed responsibility for the assaults. The so-called insider attacks incidents when an Afghan soldier or policeman turns his gun on fellow troops have been a serious problem in recent years.
In today's assault, deputy provincial police chief in northern Zawzjan province, Abdul Hafiz Khashi, said that before dawn, a traitor allowed an unspecified number of insurgents into the compound at the checkpoint in Qush Tepa district, where they killed 10 soldiers.
The attackers and Alim fled the scene and security forces were pursuing them, he added.
Also Tuesday, a roadside bombing in northern Balkh province killed five police officers, including a district police chief, according to Sher Jan Durani, spokesman for the provincial police chief in Balkh.

The five were on patrol in a vehicle in Dawlat Abad district when their car struck the bomb. Three officers were wounded in the explosion.
Meanwhile, the new Taliban leader released a message ahead of the major Muslim holiday of Eid al-Adha, saying that for peace in Afghanistan, it is necessary to "end the occupation" of the country by all foreign forces a reference to NATO troops.
His message was likely an attempt by the newly appointed Mansour to reassure followers that he is keeping in tradition with his predecessor, the late Taliban leader Mullah Mohammad Omar, in releasing messages ahead of Eid al-Adha.
"If the Kabul administration wants to end the war and establish peace in the country, it must end the occupation and revoke all military and security treaties with the invaders," Mansour in the statement.
Mansour also urged the Taliban to unite and ignore "futile enemy propaganda" about disunity among their ranks. There are still some Taliban commanders who oppose Mansour's leadership. Last week, after almost two months of differences, Mullah Omar's family announced their support for Mansour.
