A hospital in Chicago was forced to stop accepting patients as it was at full capacity following multiple gang-related shootings.

Mount Sinai Hospital had to temporarily stop letting patients in on Sunday morning, an official said.

At one point, the hospital was treating 12 shooting patients, according to Roberta Rakove, Senior VP for External Affairs.

She said it went 'on bypass' in the early morning, a term which is used when a hospital diverts ambulances to other trauma centers.

Mount Sinai Hospital is one of five trauma centers in Chicago, according to Rakove.

She did not provide any updates on the conditions of the shooting victims.

Chicago Police Public Information Officer Anthony Guglielmi told CNN that officers responded to several multi-victim shootings on the west side of Chicago on Sunday, after a gang conflict.

Police Chief Eddie Johnson gave a rundown of the shootings to media on Sunday.

He said there were three separate shootings, which resulted in 10 injuries, one of which was fatal.

The shootings are being investigated.

Before the press conference, Johnson mentioned the recent mass shootings in Dayton, Ohio, and El Paso, Texas.

He said: 'You have to stop yourself and ask what will it take before we get a handle on what's going on.

'Not only in Chicago, but across the country.'

'From police departments to the court systems to prosecutors to legislators -- we have to come together and figure out more common-sense solutions to these problems because clearly too many of our citizens are being shot and killed.'

Rakove could not say when Mount Sinai Hospital went 'on bypass,' but said it came 'off bypass' at approximately 6:30 am. It has since resumed accepting patients.

She also said the hospital had an even busier weekend last year with more than 70 people shot.

'All Level 1 trauma centers were overwhelmed, but we all managed,' Rakove said of the previous year's shootings.

'This weekend was not that kind of weekend, but it was enough.'
