The North Carolina governor has declared a state of emergency in the city of Charlotte, as unrest continues over the police killing of a black man.

The second night of protests had begun peacefully but the demonstration was interrupted by gunfire and a man in the crowd was injured. The city initially said he had been killed but then issued a clarification.

Protesters then threw bottles and fireworks at the officers, who were lined up in riot gear. Police fired flash grenades and tear gas to repel the crowds.

Violence erupted for a second night after Keith Lamont Scott was shot dead by a black officer on Tuesday.

One protester is in a critical condition after a "civilian on civilian" shooting, the city said.

Riot police in Charlotte used tear gas as they faced hundreds of protesters. The local police department said four officers were injured.

Earlier North Carolina Governor Pat McCrory said he had initiated efforts to deploy the National Guard and highway patrol to help deal with the protests.

"Any violence directed toward our citizens or police officers or destruction of property should not be tolerated," he said.

Mr Scott was the third black man killed by police in a week. Such shootings have sparked huge protests recently.
