The shooting happened just after 5:00 p.m. CST. The park is a little more than a mile away from Robb Elementary School where a gunman opened fire in May, killing 19 students and 2 teachers.
The Uvalde Police Department announced that it was investigating a "shooting with injured victims" at the park. Police urged residents to avoid the area but said that there was no immediate danger to the community at large.
According to KSAT, two juveniles have been hospitalized. Their conditions were not released, but the station says that they both were conscious when they were airlifted to a hospital in San Antonio.
Authorities are questioning at least four people in connection with the shooting, which they believe may be gang-related.
