At least one person was killed and three others injured in a shooting on a residential street in Ottawa on Wednesday, the authorities in the Canadian capital said.

Though initial alerts sent out around 8 a.m. ET suggested a gunman was at large on the 400 block of Gilmour Street, near the city center, the Ottawa Police later said they believed it was a “targeted shooting” that unfolded both inside and outside a home.

“It wasn’t an active shooter running around shooting people,” said Constable Amy Gagnon of the Ottawa Police. “It was targeted.”

She said the police were still investigating what led to the shooting, which occurred about half a mile from Parliament Hill, the home of the country’s legislature. The police said they were still looking for at least one gunman.
