Thw leader of Islamic State's branch in Afghanistan and Pakistan has been killed in a US drone strike, the Pentagon says.
The death of Hafiz Saeed Khan on July 26 is a blow to efforts by Islamic State - also known as ISIS or Daesh - to expand from its heartlands in Syria and Iraq into Afghanistan and Pakistan, already crowded with jihadist movements including the Taliban and al-Qaeda.
The fatal strike follows the killing of Afghan Taliban leader Mullah Akhtar Mansour in a US drone attack in Pakistan in May. However, Afghanistan's 15-year-old war grinds on with no clear victory in sight.
Taliban fighters have been threatening at least two provincial capitals this (northern) summer, in Helmand and Kunduz, and a US government report said Afghan forces had lost five per cent of territory this year.
In terms of its own territory, Islamic State has been largely confined to a handful of districts in Afghanistan's Nangarhar province, which borders Pakistan, where IS militants - mostly defectors from the Taliban - are blamed for raiding villages and government outposts.
