At least 14 people were killed Wednesday when gunmen opened fire at a social services facility in California, authorities said.
San Bernardino Police Chief Jarrod Burguan told a news conference that 14 others were wounded in the shooting at the Inland Regional Center and as many as three suspects were still at large.
The trio were armed with long guns, Burguan said, adding that police had not recovered any of the weapons.
He said the suspects may have fled in a black sport utility vehicle. Ports as well as local county and city buildings were placed under lockdown.
“We do not know if this is a terrorist incident,” David Bowdich, an assistant director at the FBI’s Los Angeles office, said. But Burguan said the suspects “came in with a purpose”.
President Barack Obama has been briefed on the shooting by his Homeland Security Advisor, Lisa Monaco, and has asked that he be updated as the situation develops, according to a White House official.
Authorities said no detail was available regarding the attackers’ identity, nor did they know of a motive.
The injured have been taken to nearby hospitals.
The facility where the shooting took place, provides services to people with developmental disabilities and their families, according to its website.
San Bernardino City Unified School District said its “schools and offices are on full lockdown for the safety of students and staff”.
“All schools are scheduled to dismiss students on time today,” it said in a statement.
