The body of a British trekker has been found in northern Pakistan, local officials have said.
Alexander Harris, who was originally from Birmingham, went missing on Saturday as he was descending from the summit of Musa Ka Musala, a mountain of just over 4,000m (13,000ft), in the Khyber Pakhtunkhwa province.
Khalid Iqbal, the area's deputy commissioner, said police and volunteers had been involved in a search for 30-year-old Harris and his body was found on a path in a forest, adding "most probably he slipped and fell".
He said it was suspected Harris, who had been living in Pakistan's capital Islamabad where he worked for global advisory company Adam Smith International, had slipped and fallen.
Harris, who also had Irish citizenship, had set off on the trek around 05:40 local time on Saturday with a hiking companion. They took some photos at the summit and then began to descend, before becoming separated.
"There was a difference in their speed," Iqbal said. "He [Harris] was moving faster, he got about 1-2km ahead. Then it started raining."
The deputy commissioner estimated that between 250-300 people were involved in the rescue operation including police and volunteers, searching on foot and with drones, although their use was limited by poor visibility.
A keen hiker and trail runner, Harris was a regular participant in long distance races in Pakistan.
Iqbal said the two trekkers had not told the authorities about the trip.
"The hotel had offered him a guide and police security," Iqbal says. "But he said that he knew the area and did not need any help."
In a statement, Adam Smith International said Harris was a "much loved member" of their team and that they were devastated by his death.
His company said: "He cared deeply for Pakistan, its people, its nature, and learned Urdu during his time there."
It added: "We are deeply grateful to the hundreds of people who joined the search effort, including local residents, volunteers, police, rescue teams, forest department, members of Alex's trail running community, and the government of Pakistan that supported the operation.
"They searched tirelessly in difficult conditions, often in heavy rain, fog and poor visibility, over steep and challenging terrain."
It added: "Our thoughts are with Alex's family, friends and colleagues at this incredibly difficult time. We remain focused on supporting his family."
Harris's running group, Margalla Trail Runners, posted on social media calling him "a passionate trail runner".
They added: "May his soul rest in peace and may his family and loved ones find strength and comfort during this difficult time."
The UK Foreign Office has been contacted for a response.
