It was clear that the two shooters had gone down the dark path of radicalisation, embracing a perverted interpretation of Islam that calls for war against the US and the West, Obama said.

He called on Americans not to turn against each other, saying the Muslim Americans were 'friends, coworkers' of the US.

Obama also said the country should carry out stricter screening for those who come to the US without visa. The US will continue to provide training and equipments to thousands of Iraqis, he said.

According to local police, 'some degree of planning' was involved in the shooting spree. Obama's address came less than a week after southern California shooting spree, and less than a month after the deadly attacks in Paris, for which the IS had claimed responsibility.

The November 13 attacks in Paris left at least 130 people killed and over 350 others injured.
