Nato says two of its soldiers have been killed in fighting in southern Afghanistan.
The troops had died in "separate engagements with enemy fighters", a statement from Nato's International Security Assistance Force (Isaf) said.
In eastern Paktika province, a district police chief was killed in a roadside bomb explosion, local officials said.
Fighting between Nato-led forces and the Taleban has escalated in recent weeks, particularly in the south.
The Ministry of Defence later confirmed that one of the two troops killed was British.
The soldier, who has not been named, was shot dead in Helmand province early on Wednesday morning, a statement said.
The nationality of the other soldier has still not been announced.
Paktika Governor Moahmmad Akram Khpalwak told the BBC the police chief of Yahya Khel district had been trying to defuse the roadside bomb when it went off.
He died later of his injuries, the governor said.
