"Canada strongly condemns yesterday's attack on a convoy of cars carrying local leaders and supporters of India's ruling Congress party in the country's east," Canadian Foreign Minister John Baird said yesterday in a statement.
"This violent extremism is despicable and is a stark reminder of the grave threat that terrorism poses to the people of India and the region. We expect that the perpetrators of this horrendous attack will be brought to justice," he said.
"On behalf of all Canadians, I extend my deepest sympathies to the victims' families and friends, and I wish a swift recovery to the injured," he said.
