OTTAWA - Prime Minister Justin Trudeau is calling the attack on a gay nightclub in Florida an act of domestic terror.

Trudeau says he was "shocked and saddened" to learn so many people were killed and injured following the mass shooting in Orlando.

Trudeau says that while authorities are still investigating and not all details have been confirmed, it is "appalling that as many as 50 lives may have been lost to this domestic terror attack targeting the LGBTQ2 community".

Trudeau says he and his wife, Sophie Gregoire Trudeau, are offering condolences and prayers to the families and friends of those lost and wish full recovery to those who were injured in the attack.

Trudeau says they stand in solidarity with Orlando and the LGBTQ2 community, grieve with their friends in the United States and Florida.
