Somali militant group al-Shabab says it has killed five men it accuses of spying - one of them for the UK.
According to a jihadi website, he had admitted giving information to British intelligence services about al-Shabab supporters living in the UK.
The five men, aged between 22 and 36, were shot dead in a public execution on Tuesday in an area under the control of the Islamist group.
That individual is alleged to have attached a device to a vehicle in an al-Shabab convoy which had then helped American drones to carry out an air strike.
Al-Shabab told Reuters news agency that three of the men were US spies who had helped guide drones to carry out strikes in Somalia.
The UK, US and Somali governments have not yet commented on the reports.
The identity of the alleged British spy has not yet been confirmed, despite earlier reports that he was a British national.
Al-Shabab, which is part of al-Qaeda, was forced out of the capital, Mogadishu, in 2011 by a combination of Somali government forces and African Union troops but it still operates freely in many rural parts of southern Somalia, where it often enforces Islamic law, or Sharia.
In December 2017, al-Shabab killed five men, among them a teenage boy, whom it accused of working for US and Kenyan intelligence.
As well as battling for control of parts of Somalia, al-Shabab has staged terror attacks across East Africa.
The group was also behind Somalia's deadliest bombing, in which at least 500 people were killed by a truck laden with explosives in Mogadishu last year.
