PITTSBURGH (AP) — A man armed with two semiautomatic handguns entered the lobby of a psychiatric clinic at the University of Pittsburgh on Thursday and opened fire, killing one person and wounding several others before he was shot dead, apparently by campus police, the mayor said.

Six people were wounded by the man's gunfire, Mayor Luke Ravenstahl said. A seventh suffered unspecified injuries but wasn't shot, officials said.
