The casualty toll among civilians in October increased by 55 percent against September, while the casualty toll among insurgents and security forces increased by nearly 25 percent, the study revealed.
"The insurgents' movements reduced in the month of September and the security forces have had a chance to prevent their activities in the month of October. But it did not happen and insurgents' movements increased in October," Sayed Abbas Hussaini, a TOLOnews researcher, said as quoted by the media outlet.
Afghanistan is in a state of political and social turmoil, with government forces fighting the continuing Taliban insurgency. The instability has persisted in the country since the 2001 US-led invasion to defeat the Taliban and al-Qaeda in the wake of the 9/11 attacks in the United States.
The Islamic State (IS) terrorist group, outlawed in many countries including the United States and Russia, has also increased its presence in the country and in neighboring states.
