At least 14 people were dead and another 17 injured in a shooting in San Bernardino, California, when a trio of gunmen who were heavily armed and ‘on a mission’ opened fire during a function at a center for people with developmental disabilities, police said.The heinous attack took place at local time 11am on Wednesday.Up to three shooters, armed with assault weapons and ‘prepared to do what they did as if they were on a mission,’ opened fire at the Inland Regional Center, San Bernardino Police Chief Jarrod Burguan said.Investigators were still trying to determine a motive, but have not ruled out terrorism.‘We have no information at this point to indicate that this is terrorist related in the traditional sense that people may be thinking. Obviously at minimum we have a domestic terrorist type situation that occurred here,’ Burguan said. The FBI later said that terrorism was a ‘possibility.’As news spread, Barack Obama condemned the mass shooting – and the lack of political action to prevent them taking place – in an interview with ABC News. ‘We have a pattern now of mass shootings in this country that has no parallel anywhere in the world,’ he said.
