Three U.S. service members have been killed in southern Afghanistan, NATO officials said Saturday.
The international coalition said the victims were not participating in a major offensive under way in the Taliban stronghold of Marjah in Helmand province.
NATO said the Americans died following a bombing, but it provided no other details.
Afghan National Army Maj. Abdul Rahman says international troops were killed when suicide bomber on a motorbike targeted a joint foot patrol of Afghan and U.S. soldiers in Kandahar province, which lies next to Helmand. NATO would not confirm if it was the same incident.
Separately, NATO says a Canadian soldier has died of injuries he suffered in a training accident Friday on a shooting range northeast of Kandahar.
