NATO says an Afghan army soldier has killed four foreign soldiers in eastern Afghanistan.
An Afghan intelligence security source says the four were French troops.
Seventeen others were wounded by the rogue soldier in the Taghab valley of eastern Kapisa province on Friday, Reuters reports.
The gunman has been detained.
Meanwhile, six NATO soldiers have been killed in a helicopter crash in Helmand province in the south on Friday.
The nationalities of the victims have yet to be released.
It is the worst crash since August last year when 30 soldiers, including 22 elite navy SEAL commandos, died when their helicopter came down in eastern Afghanistan.
The Defence Force says it is highly unlikely that any New Zealanders were involved.
