Since coming to power in Afghanistan three months ago, the Taliban have been waging a counterinsurgency campaign, vowing to put down the threat from IS.
IS is an enemy of the Taliban. The two groups share a hardline interpretation of Islam and over the years engaged in some of the same violent tactics, such as suicide bombings. However, the Taliban have focused on seizing control of Afghanistan, while IS adheres to global jihad.
On Wednesday, a spokesman for the Taliban intelligence service told reporters in Kabul that the agency has arrested close to 600 IS members, including key figures and financial supporters. The spokesman, Khalil Hamraz, said at least 33 IS members have been killed in gun battles with Taliban security forces.
