夏洛特市连续第二晚发生暴力冲突

One person was shot late Wednesday in the city of Charlotte, North Carolina, as protesters rallied for a second night in response to the police killing of an African-American man.

The governor of North Carolina declared a state of emergency in Charlotte and deployed National Guard troops in the city.

Early in the night there were peaceful marches, but they later turned violent with clashes erupting between police in riot gear and protesters. Officers fired tear gas to try to disperse crowds. Some people smashed store windows and set small fires in streets.

The situation was largely calm by the early hours of Thursday.

The city government initially said someone was killed Wednesday night when shot by another civilian, not police, but later said that person was critically injured. Charlotte's police department said four officers were also hurt, none with life-threatening injuries.

On Tuesday, the first night of protests, there were about 24 people injured, including 16 police officers.

Mayor Jennifer Roberts appealed for calm, saying Charlotte has always been a place where people can have peaceful dialogue.

The protest come in response to Tuesday's shooting of 43-year-old Keith Lamont Scott at an apartment complex. Police said officers were looking for someone else when they saw Scott come out of a car with a gun, and that the officer fired after Scott ignored warnings to drop it.

Scott's family says he was unarmed, and was instead carrying a book when he was shot. Witnesses said he had his hands in the air.
