KABUL, Afghanistan (CNN) -- Two coalition soldiers and three Afghan civilians were killed in southern Afghanistan Thursday in a suicide attack, the NATO-led military force in Afghanistan said.
The International Security Assistance Force said the explosives that detonated were used in a "vehicle-borne suicide IED strike," a reference to an improvised explosive device. ISAF gave no other details.
"Our sincere condolences go out to the families and friends of the brave soldiers who died during this horrific attack," said Brig. Gen. Richard Blanchette, spokesman for the International Security Assistance Force.
"This attack merely strengthens ISAF's resolve to support the people of Afghanistan in their fight against an insurgency that seeks to undermine their security," he said in a written statement.
The nationalities of the soldiers were not released.
On Wednesday, a Canadian soldier was killed when a roadside bomb struck the armored vehicle in which he was riding, officials said.
Three other Canadian soldiers were wounded in the attack north of Kandahar, the Canadian defense ministry said.
The death of Trooper Brian Richard Good brings the number of Canadians killed in Afghanistan to 107 since the coalition's invasion in October 2001 to dislodge the Taliban and al Qaeda.
Canada has suffered the third highest number of deaths among coalition partners, behind the United States and Great Britain.
