A Canada Border Services Agency guard was shot just before 2 p.m. Tuesday on the Canadian side of the Peace Arch border crossing. She was airlifted to a Canadian hospital around 3 p.m., and her condition is unknown.
U.S. Customs and Border Protection spokesman Mike Milne confirmed the incident Tuesday, and said the Peace Arch port of entry is closed to all traffic in both directions. Drivers wishing to cross into Canada should use the Pacific Highway crossing in Blaine or travel through Lynden or Sumas.
Unconfirmed reports suggest the shooter, who shot himself in the head after shooting the guard, was driving a white vehicle with Washington plates.
