A teacher and a student have been shot dead in a murder-suicide at an elementary school in San Bernardino, California.
Police confirm that people have died in the shooting at a Southern California social services center.
The two young suspects of California shooting are of Pakistani origin, media reports have said even though President Barack Obama has asked people not to rush to a conclusion.
Law enforcement officials in San Bernardino said they could not rule out terrorism as a possible motive for the mass killings at a centre for people with disabilities that left 14 people dead and 17 others injured.
The Pakistani-origin gunman who carried out the massacre of 14 people in California along with his Pakistani wife may have been radicalised as he was in touch with extremists, officials said.
