Austin Police said two separate shootings occurred in the city's entertainment district minutes apart
One woman was killed and three people were hospitalized with bullet wounds in overnight shooting incidents in the Texas capital of Austin, emergency officials said on social media early on Sunday .
Austin police said in a message on Twitter there had been "separate shootings within the same area" of the city's downtown, adding: "Both scenes are secure at this time."
The Austin-Travis County Emergency Medical Services agency said on Twitter that one woman had been killed and two other women and one man taken to hospital with gunshot wounds.
A fourth person was also hurt but declined medical treatment, according to the social media post from the agency.
Austin Police Chief Brian Manley told reporters two separate shootings occurred in the city's entertainment district minutes apart.
"Given the fact we had just had multiple shots fired on sixth street then we have another incident occur several blocks away with shots being fired in that incident, the initial concern was that we had an individual that was engaging in active shooter tactics in the entertainment district but again, that is not what our assessment is at this point, these were two isolated incidents" said Manley.
The shootings follow several major acts of gun violence in the United States over the past several weeks.
On June 12, a gunman who sympathised with Islamist extremist groups killed 49 people at a nightclub in Orlando, Florida, in the deadliest mass shooting in modern US history.
On July 7, a US military veteran shot and killed five police officers in Dallas in the deadliest day for US law enforcement since the September 11, 2001,attacks.
Just over a week later another gunman killed three officers in Baton Rouge, Louisiana. Both attackers were killed by police.
