US President Barack Obama said in a nationally televised speech on Sept. 11, that the U.S. and a large coalition will "degrade and destroy" the terrorist group known as IS. Obama said the U.S. will not hesitate to take action against Islamic State militants in Syria as well as Iraq.
Speaking from the White House the president outlined a four-point strategy against the so-called Islamic State, which Obama described as being neither Islamic, nor a state.
Obama said he said that any group that threatened America would "find no safe heaven."
He also announced that 475 US military personnel would be sent to Iraq but said they would not have a combat role.
IS controls large parts of Syria and Iraq after a rapid military advance.
Its fighters have become notorious for their brutality, beheading enemy soldiers and Western journalists on video.
The US has launched over 150 airstrikes against the group in Iraq and provided arms to Iraqi and Kurdish forces fighting against IS.
President Obama vowed that America would lead "a broad coalition to roll back" IS.
"Working with the Iraqi government, we will expand our efforts beyond protecting our own people and humanitarian missions, so that we're hitting ISIL targets as Iraqi forces go on offense," he said.
The battle against IS will include fighting them on the financial front - denying them financial support - and preventing fighters from outside the Middle East from joining the ranks of IS and preventing those in the Middle East from going back to Europe of the U.S.
Obama accused the IS of unusual brutality, of beheadings and of selling captured women into slavery.
