PITTSBURGH (AP) — Pittsburgh's mayor says a gunman who opened fire after entering the lobby of a psychiatric hospital at the University of Pittsburgh was armed with two semi-automatic handguns.

Mayor Luke Ravenstahl says the man exchanged gunfire with police and was shot dead Thursday but not before one person was killed and seven others were hurt, apparently by his gunfire.

One injured person wasn't hurt by gunfire.

The mayor stops short of confirming the gunman was fatally shot by a University of Pittsburgh police officer. But he confirms "police acted admirably and did engage in gunfire."

One of the injured was a police officer who Ravenstahl says was grazed by a bullet. Officials aren't saying if the officer shot the gunman.
