At least two Japanese tourists were killed and 11 wounded when a knife-wielding man went on a stabbing spree outside a resort in the Pacific island nation of Guam, officials said Wednesday. The attack occurred late Tuesday when the man drove his car up a pavement near the Outrigger Guam Resort and rammed it into a convenience store, before jumping out and stabbing bystanders. The Japanese foreign ministry said it had been informed of two fatalities and 11 injuries.
