At least 12 people have been reported killed and several injured following a shooting incident in the US state of California, with at least one "active" shooter still at large, local authorities say.
The San Bernardino Sheriff's Department told Al Jazeera that the incident took place at the Inland Regional Centre, a local service centre in the city - located about 100km east of Los Angeles.
Police also confirmed to Al Jazeera that there were 12 fatalities.
In a statement following the shooting, US President Barack Obama told US broadcaster CBS that there's a pattern of mass shootings across the country "that has no parallel anywhere else in the world".
"There are steps we can take to make Americans safer, and we should do so in a bipartisan manner," he said.
For those concerned with terrorism, Obama said that there's a no-fly list barring people getting on planes, but those same people are allowed to buy guns.
The fire department said in a tweet that it was responding to reports of a "20 victim shooting incident", which took place at about 11am local time [19:00 GMT].
