Afghanistan ? A roadside bomb tore through a NATO vehicle on Wednesday, killing six soldiers and their Afghan interpreter in a southern Afghan region that has recently seen heavy fighting, a NATO statement said.

NATO did not release the soldiers’ nationalities or the location of the attack, but Afghan police said it happened in Kandahar province’s Zhari district. The majority of the troops in Kandahar are Canadian.

Canadian Defense Department spokeswoman Sarah Kavanagh said had no information on the incident.

The attack was the deadliest against foreign troops in Afghanistan since May 13, when seven troops were killed – five Americans, a Canadian and a Briton – when the Chinook helicopter they were riding in crashed in Helmand province. Officials at the time said it appeared a rocket-propelled grenade might have brought the aircraft down.
