AKIPRESS.COM - Dozens of Afghan security personnel and Taliban fighters have been killed as battles continue to rage across four northern provinces, BBC reports.
Afghan officials say that without reinforcements the capital of Sar-e Pul province could fall to the Taliban, which launched attacks on Sunday night.
Key areas of Jawzjan province had fallen to the Taliban, officials said.
The violence follows recent diplomatic efforts to end the lengthy war between the Afghan government and the Taliban.
A spokesman for the Sar-e Pul provincial governor reportedly said militants were gathering to the east of Sar-e Pul city, warning "the centre will fall to the Taliban" if the government did not send more troops.
A Taliban spokesman meanwhile said their fighters had taken checkpoints no more than five kilometres (3 miles) from the city centre.
Government forces have suffered several setbacks in recent weeks in their battles against the Taliban.
