Police in Austin, Texas said that an "active shooter" today caused "multiple victims," with local media reports saying that at least one person was dead.
Police said via Twitter there were separate shootings downtown "within the same area," and that "both scenes are secure at this time."
A woman in her 30s was killed in the incident, the Austin American-Statesman newspaper reported, citing county emergency medical personnel.
At least three other people were rushed to a local hospital, the newspaper said. Police across the country, and especially in Texas, remain on edge weeks after a black extremist shot dead five officers protecting a peaceful march against police brutality in Dallas.
