Gunman kills two in Portland, Oregon

PORTLAND, Oregon (Reuters) - A gunman killed two people in a strip mall in Tualatin, a small city south of Portland, Oregon, police said on Tuesday.

The suspect was in custody, according to police in Tualatin, 13 miles from Portland. Two other victims are being treated in hospital after the shooting, which took place at a drug-testing facility, the police said in a statement.

There is a heightened awareness of shootings in the United States after 13 people were killed and 30 wounded by a gunman at the Fort Hood U.S. Army base in Texas last week.
