• The White House has been briefed on the explosion and is monitoring the situation. Canadian prime minister Justin Trudeau has also been briefed and is monitoring it.
• Canadian officials held a briefing on the explosion. Dominic LeBlanc, Canada’s public safety minister, declined to comment on the cause of the crash as they did not have “reliable verified information.”

• Two male occupants in the vehicle involved in the explosion are deceased, CNN reported.
• A witness that saw the crash said the vehicle involved looked like it was traveling “over 100 miles an hour.”
