At least 28 Islamic State and Taliban militants were killed in US drone strikes in two provinces in Afghanistan and a restive tribal region in Pakistan at the weekend.
"Twenty Daesh affiliates have died in drone strikes by NATO in Achin district," said Hazrat Hussain Mashriqiwal, police spokesman in the eastern Afghan province of Nangarhar, on Sunday, using an Arabic acronym for the Islamic State extremist militia.
"At least three foreign militants died in Kunar province on Saturday when a drone ... hit them in ... Shegal district," said Abdul Latif Fazli, a provincial council member from the eastern Afghan province of Kunar.
Fazli said the militants were part of the Taliban and had come from Pakistan.
On Saturday, five militants were killed in Pakistan's restive tribal region in a drone strike that targeted a rebel hideout in the mountainous Shawal valley area of North Waziristan.
A security official said the dead included senior Pakistani Taliban commander Noor Saeed. He said some militants were also injured.
It was the first attack of 2016 and came after the Bureau of Investigative Journalism reported Thursday that drone strikes in Pakistan dropped to an eight-year low - just 13 last year - after peaking at 128 in 2010.
