US: 9 injured in shooting at Kansas nightclub

The shooting in a Kansas nightclub early on Sunday morning left seven people with gunshot wounds and two more people hospitalised after being trampled as people fled, police said.

Shots were fired just before 1am in the City Nightz nightclub on North Washington Street, Wichita Police Lt. Aaron Moses said during a press conference at the scene.

The shootings were part of a particularly violent night in Wichita, a city of nearly 4,00,000 people about 200 miles (320 kilometres) southwest of Kansas City, Missouri.

According to the police department's Facebook page, a 17-year-old boy was found dead around 6.30pm on Saturday.

Investigators said it appears he was shot during an argument with a 21-year-old man, who showed up at a hospital with a gunshot wound to his hand. 

About twenty minutes after the shootings at City Nightz on Sunday morning, a 35-year-old man was walking down a road when an unknown suspect shot him in the arm.
