San Bernardino attack: US 'will not be terrorised' - Obama

President Barack Obama says the US "will not be terrorised" by Wednesday's mass shootings in San Bernardino, California.

"We are strong. And we are resilient," he said in his weekly radio address, adding that it was "entirely possible" the two attackers had been radicalised.
Syed Rizwan Farook, 28, and his wife Tashfeen Malik, 27, killed 14 people before being shot dead by police.

The FBI is investigating the shootings as an "act of terrorism".
The Islamic State militant group on Saturday hailed the attack, saying it had been carried out by "two supporters of the Islamic State".
The statement, carried by IS's al-Bayan radio, gave no indication that the group had any involvement in planning the shootings at the Inland Regional Center social services agency.
