Chicago carnage: gunman goes on rampage inside hospital
A gunman opened fire outside Mercy Hospital in Chicago's South Side, reportedly targeting a woman in scrubs and shooting a police officer before being shot himself.
Chicago police department said there were "multiple victims" following the shooting at 3.30pm local time.
Anthony Guglielmi, spokesman for Chicago police department, said there were "reports of multiple victims", and added that officers were going throughout the hospital, searching for the gunman.
He added that at least one "possible offender is shot", but there were no further detaila last night.
He said that the shot officer was "in critical condition but receiving excellent care".
At least 10 ambulances were on the scene, and Rahm Emanuel, the mayor of the city, was meeting with Eddie Johnson, superintendent of Chicago police, to assess the situation.
Mr Guglielmi tweeted yesterday: "Avoid area. Heavy police presence incoming."
Chicago has in recent years earned an unwelcome distinction for its violence.
From 2015 to 2017 the city registered nearly 1,900 murders - a period during which the next-closest city, Baltimore, registered around 1,000.
However, the city is not in the top 10 for murders nationwide, per capita.
St Louis in Missouri has had the nation's highest murder rate since 2014, with 66.1 murders per 100,000 people in 2017, according to the FBI.
