BLAINE, Wash. — The Peace Arch crossing on the US-Canada border was closed Tuesday after a man driving a van with Washington state plates shot a Canadian guard in the neck and then apparently killed himself, a police official said.
Royal Canadian Mounted Police Corporal Bert Paquet told reporters the Canadian Border Services Agency officer was breathing when she was flown to a hospital, but he had no further details on her condition.
The officer was in her booth when she was shot. Investigators were trying to figure out what happened and why, Paquet said.
They had not confirmed whether the suspect was the van’s owner.
The Peace Arch crossing in Blaine is the third busiest port of entry on the northern border. Last month, it averaged 9,000 US-bound cars a day, according to US Customs and Border Protection.
The crossing features a park with a 67-foot-high monument in the form of an arch that connects the United States and Canada.
Canadian Brian White told reporters at the scene he was waiting to cross northward when he heard the shot.
He said guards immediately responded, and there were people screaming. Officials questioned everyone waiting to cross and took their car registration information.
The wounded officer’s identity and other personal details were withheld. Paquet said US authorities were notified of the incident.
‘‘This is a very serious incident that occurred right on the border line,’’ he said. ‘‘We are sharing information with them.’’
