Government forces in Nangarhar confirmed clashes between the Taliban and IS offshoots, but army spokesman Atefi said they were not targeting IS militants.
Achin's district chief, Malek Islam, also said Afghan forces were not confronting IS fighters, who he said were "almost everywhere in the district", but were targeting the Taliban.
"They (IS) haven't attacked us, and we haven't engaged them either," he said.

Interesting.. Very Interesting.. So Afghan forces are not engaging IS and are only attacking Afghan Taliban. So Taliban is getting hit from both side - Afghan forces and ISIS..
This should further complicate equations of few countries.
