LAVEEN, AZ - Phoenix police say a head-on collision Monday morning in Laveen has left three young brothers dead, and several of their siblings injured.
Air15 video showed more than a dozen Phoenix fire and police vehicles near Southern and 59th avenues after the crash happened around 7 a.m.
Phoenix police said a mini van with seven people inside is believed to have lost control while traveling westbound on Southern Avenue and crashed into a passenger vehicle.
The passengers inside the minivan -- brothers and sisters headed to their first day of school -- were all under the age of 16, police said. The driver, a 16-year-old boy, reportedly did not have a license.
Police believe the teen was impaired at the time of the crash. Authorities are still waiting on blood test results to determine if he was drinking or on drugs.
The names of those killed haven't been released, but police say the boys were ages 5, 8 and 11.
The force of the crash caused at least three of the children to be ejected from the vehicle, according to Sgt. Trent Crump. Witnesses called 911, and when police arrived, they found several children who were thrown into the brush.
The seven siblings, along with the driver of the sedan, were all transported to local hospitals.
Police say three other children remain hospitalized, including a 4-year-old girl who's in critical condition.
The man in his 40s who was driving the sedan also is listed in critical condition.
