The Afghan Taliban announced on Tuesday that it was freeing a US national who had been detained for more than a year.

The foreign ministry said the family of linguist and researcher Dennis Coyle had written to the supreme leader of Afghanistan, requesting his release for Eid.

“The Supreme Court of the Islamic Emirate deemed his period of detention sufficient and decided on his release,” a statement read.

The announcement came after a meeting of Foreign Minister Amir Khan Muttaqi, US former special envoy to Afghanistan Zalmay Khalilzad, United Arab Emirates’ (UAE) ambassador to Kabul Saif Mohammed Al-Ketbi, and a member of Coyle’s family.

The UAE facilitated the release, the ministry said, adding that Coyle had been reunited with his family in Kabul on Tuesday.

Coyle, 64, was arrested by the Afghan authorities in January 2025, according to the Foley Foundation, which advocates for the release of Americans taken hostage or arbitrarily detained abroad.

US Secretary of State Marco Rubio also welcomed Coyle’s release, and urged the Taliban authorities to release all other detainees.

“Dennis joins over 100 Americans who have been freed in the past 15 months,” he said, adding that the United States was “still seeking the immediate return of Mahmood Habibi, Paul Overby, and all other unjustly detained Americans”.

A website set up by his family, freedenniscoyle.com, said he was “legally working to support Afghan communities as an academic researcher” when he was detained.

They said he had been held in “near-solitary conditions, requiring permission even to use the bathroom, and without access to adequate medical care”.

Coyle first travelled to Afghanistan in the early 2000s “to survey Afghanistan’s rich linguistic diversity and help Afghan communities develop resources in their own languages”, they added.

“Throughout his years of service, Dennis maintained a home in Kabul and built deep, meaningful relationships with the Afghan people,” the website read.

“Those who know him speak with profound appreciation for both the man and his work. Dennis has always embraced Afghan culture with genuine warmth — sharing cups of traditional green tea, enjoying dried fruit snacks, and engaging in the kind of heartfelt conversations that bridge cultures,” it said.

“His love for the Afghan people isn’t just professional; it’s personal and deeply felt.”

Earlier this month, Rubio said the country had formally placed Afghanistan on its list of countries engaged in “wrongful detentions”.

The Afghan authorities called it “regrettable” and pointed to talks between the two sides and previous releases with mediators from Qatar.

In 2025, five American citizens were released in what the Taliban authorities said was a “goodwill gesture”.
