A British tourist was among three people killed in a national park in Uganda on Tuesday, in a suspected attack by a group linked to Islamic State.
A South African tourist and a Ugandan guide were also killed.
The trio were driving through the Queen Elizabeth National Park when they came under attack from the Allied Democratic Forces (ADF) rebel group, police spokesman Fred Enanga said.
“The three were killed, and their safari vehicle burnt,” Mr Enanga said in a post on Twitter.
“Our joint forces responded immediately upon receiving the information and are aggressively pursuing the suspected ADF rebels,” he added.
Police did not say exactly where the attack had taken place. The national park’s western boundary is the shore of Lake Edward, which separates Uganda from Congo.
In a statement, the Uganda Wildlife Authority said: “We regret to report that all three individuals were attacked today evening and killed by unknown assailants, who also set their vehicle ablaze.
“The deceased, whose names are withheld, include a Ugandan, a UK citizen and a South African citizen.”
The group was travelling with a local tour company, the statement added.
The ADF began as an uprising in Uganda but has been based in the Democratic Republic of Congo since the late 1990s. It pledged allegiance to Islamic State in mid-2019 and is accused of killing thousands of villagers in frequent raids over the past decade.
Rebels from ADF have previously carried out attacks in the area and across the border in Congo where they have bases.
Last week, ADF fighters killed at least one man and injured another when they ambushed a truck in western Uganda.
A UK foreign office spokesperson said: “We are liaising with local authorities to ascertain more details. We stand ready to support the Ugandan authorities.”
