Taliban insurgents launched separate attacks on Afghan security forces in the country's north, killing at least 52, provincial officials said on Monday.

Mohammad Yusouf Ayubi, head of the provincial council in Kunduz province, said that at least 13 security forces were killed and 15 others wounded in an attack on a checkpoint they were manning in Dashti Archi district. The firefight began late on Sunday and continued into Monday morning.

Meanwhile in Jawzjan province, Provincial Police Chief Gen. Faqir Mohammad Jawzjani said the Taliban attacked Khamyab district from different sides, forcing Afghan forces to withdraw from the district headquarters to avoid civilian causalities.

“There was intense fighting and we didn't want civilian houses destroyed, or any civilian casualties,” said Jawzjani. He said that at least eight policemen were killed and three other police were wounded. Seven Taliban were killed and eight were wounded during the gun battle, he added.

Taliban spokesman Zabihullah Mujahid claimed responsibility for the group for the attacks in Kunduz and Jawzjan provinces.

The Taliban also killed another 14 local Afghan policemen and pro-government militiamen in the Dara Suf district of Samangan province, provincial spokesman Sediq Azizi said, adding that six others were also wounded.

Azizi added that three Taliban fighters were killed and four others wounded during the Monday morning battle.

No one claimed responsibility for the attack in Samangan, but Azizi blamed Taliban insurgents that are active in the province and often target Afghan security forces and local, pro-government militias.

Meanwhile in the northern Sari Pul province, the provincial governor, Zahir Wahdat, said that the Taliban killed at least 17 Afghan security forces and wounded three others in attacks across the province.

He said that 39 Taliban fighters were killed and 14 others were wounded in the battles, adding that the death toll could rise.

Gen. Abdul Qayum Baqizai, the provincial police chief, said at least two security forces were killed in the battles.

“The Taliban's attack has been repelled, but sporadic gun battles are underway at the outskirts of the city,” Baqizai added.

The Taliban hasn't yet commented on the fighting in Sari Pul province.

Since a June cease-fire that marked the Islamic holiday of Eid al Fitr, Taliban insurgents have ramped up attacks against Afghanistan's security forces killing hundreds of security personnel in increasingly well-coordinated assaults across the country.

During the three-day cease-fire, pictures circulated of Taliban arm-in-arm with Afghan security forces, singing and taking selfies together. Outraged Mohammad Yaqub, the son of the Taliban's founder, Mullah Mohammed Omar, circulated a harshly worded audio tape condemning the fraternisation.

Since then attacks against military installations have been relentless, and on several occasions the Afghan National Security Forces (ANSA) have been outgunned and out maneuvered. Even Washington's watchdog, the Special Inspector General for Afghanistan's Reconstruction (SIGAR), in successive reports noted weaknesses within the security forces, including desertions, inadequate training and corruption.

Since 2014 ANSA has taken the lead in the war against insurgents, with the US and Nato providing support and training. Yet the Taliban have increased in strength and, according to the special inspector general, nearly half the country is either under their direct control or deeply influenced by them.

A local affiliate of the Islamic State group has also emerged in the past years and carried out brazen and increasingly deadly attacks, most often targeting civilians and the country's minority Shiite Muslims. The Taliban and the Islamic State affiliate are enemies and have attacked each other's forces. The Taliban has also denied responsibility for attacks on Shiites, which IS has claimed.
