Authorities in the US state of California say eight people have been killed and several others were injured in a mass shooting at a train yard in San Jose.
The shooting took place on Wednesday morning at the Valley Transportation Authority (VTA), the city’s transit service, which is located next door to the Santa Clara County Sheriff’s Department.
“I can confirm at this point, that there are eight victims that are pronounced deceased,” Sheriff’s Deputy Russell Davis told reporters.
He said the alleged attacker, confirmed to be a VTA employee, was also dead from a self-inflicted gunshot wound, while multiple victims were being treated for “major injuries”.
The mass shooting, which drew messages of concern and condemnation from US lawmakers, is the latest in what has become a common occurrence in the United States.
“It feels like this happens over and over and over again, rinse and repeat, rinse and repeat,” California Governor Gavin Newsom said. “It begs the damn question: What the hell’s going on in the United States of America? What the hell’s wrong with us?”
Multiple local news outlets identified the alleged shooter as 57-year-old Samuel Cassidy, who was a technician at the light rail yard. Authorities have not yet confirmed the shooter’s name and have yet to offer information on a possible motive.
Cassidy had worked for the transit authority since at least 2012, when he was listed as an “electro-mechanic”, and he was promoted to “substation maintainer” in 2015, according to records posted by the nonprofit website Transportation California.
Al Jazeera’s Rob Reynolds, reporting from San Jose, said the bomb squad “is going very meticulously over the entire scene” where the shooting took place and is expected to work through the night.
San Jose Mayor Sam Liccardo said he was aware of news reports of a fire at Cassidy’s house.
“That is certainly the information that I have, is that there was a fire at the shooter’s home, there was nobody found inside the home, thank God,” Liccardo told television station KGO. “This is every mayor’s worst nightmare.”
Multiple fire department, police and bomb squad vehicles were still parked outside the suspect’s house, along a cul-de-sac in southeastern San Jose, hours after the shooting.
An explosives-detecting robot sat in the street near the home while two bomb squad technicians entered the ranch-style house. Arson investigators along with agents of the FBI and US Bureau of Alcohol, Tobacco, Firearms and Explosives were also present.
Glenn Hendricks, the chairman of the VTA board of directors, said the shooting happened in the light rail maintenance yard, where vehicles are repaired and dispatched, not inside the train system’s operations control centre.
Davis said the first calls about the shooting came in at 6:34am local time (13:34 GMT).
The city of San Jose, which has a population of just over one million, is located about 67km (42 miles) southeast of San Francisco and is in the heart of Silicon Valley.
The region is a major technology hub and home to Apple, Facebook and Google, among many other tech companies.
Mass shootings have become commonplace in the US, with at least 12 people killed in such incidents across the country during the past weekend.
Over four weeks in March and April, the US saw three such shootings that involved mass casualties: On March 16, eight were killed, including six women of Asian descent, at Atlanta-area spas; less than a week later, 10 died at a supermarket shooting in Colorado and a few weeks after that, eight were killed at a FedEx facility in Indianapolis.
“I’m horrified that our nation the Santa Clara community keeps witnessing more more acts of gun violence,” tweeted Democratic US Representative Zoe Loefgren, whose congressional district includes most of the city of San Jose.
To the families of those killed in San Jose this morning – my heart is with you. To those injured – I am hoping for fast full recoveries.
I am horrified that our nation the Santa Clara County community keeps witnessing more more acts of gun violence.

Nearly 40,000 Americans die each year due to guns, with half of that total being suicides.
Meanwhile, US legislators regularly promise but fail to pass meaningful gun law reforms.
In recent years, Democrats have called for universal background checks, which are broadly popular among Americans, as well as a ban on military-style “assault” weapons, but conservatives remain steadfastly against strict, new gun control measures.
Following the Indianapolis shooting last month, President Joe Biden declared: “This has to end. It’s a national embarrassment.” He also called on Congress to ban assault weapons and large-capacity ammunition magazines.
The White House said Biden had been briefed on Wednesday’s shooting by his US Homeland Security adviser, Liz Sherwood-Randall.
Vice President Kamala Harris, a former California attorney general and US senator, noted she has family in San Jose and called the shooting “absolutely tragic”.
“My prayers and thoughts are with all of those families affected,” she said.
