Kabul, Afghanistan (CNN) -- Fourteen militants and three international troops died in fighting over the past 24 hours in Afghanistan, authorities said Saturday.
Eleven insurgents died in an overnight raid by Afghan and NATO-led troops in Sistanay, a village in the Nad-e-Ali district of Helmand province in southern Afghanistan, NATO's International Security Assistance Force said.
A "sizeable amount" of black tar opium and a small weapons cache and bomb-making materials were found in the operation, they said.
In eastern Paktika province Friday night, forces called in an airstrike against militants planting roadside bombs, ISAF said. Three militants, including a commander of the Haqqani network, were killed.
In Khost province, just north of Paktika, a roadside bomb Saturday struck the vehicle of the sub-governor of Bak district, who received minor injuries.
The British Defense Ministry said two British soldiers were killed while on foot patrol in Helmand on Friday. The NATO command said an ISAF service member was killed Saturday but didn't list the nationality or location of the incident.
