THE CANADIAN PRESS -- OTTAWA - Prime Minister Stephen Harper says Canada stands with Norway after at least seven people were killed in an explosion in Oslo and shooting broke out at a youth camp.
Harper said he was "shocked and intensely saddened," and that Canada condemns the acts of violence.
The prime minister said Canadians' thoughts and prayers are with the victims, witnesses and all those affected.
Police in Norway say a man arrested after the youth camp shooting is likely also linked to the Oslo bombing.
There were no details about the man, who was dressed in a police uniform when he opened fire.
An unconfirmed report suggests as many as 25 may be dead at the camp.
At least seven people were killed earlier in the bombing at a government building in Oslo.
