Four other Canadian soldiers were injured in the incident, which occurred during a routine patrol about 12 miles (20 km) west of Kandahar, in the Taliban stronghold Zhari district.

Helicopters were used to evacuate the soldiers to the medical unit at at Kandahar airfield. The wounded soldiers are in stable condition and have contacted their families, Ottawa added.
