6. SOUNDBITE (English) Barack Obama, US President:
"We have to confront the warped ideologies espoused by terrorists like al-Qaida and ISIL (referring to the Islamic State group), especially their attempt to use Islam to justify their violence. I discussed this at length yesterday. These terrorists are desperate for legitimacy and all of us have a responsibility to refute the notion that groups like ISIL somehow represent Islam, because that is a falsehood that embraces the terrorists' narrative. At the same time we must acknowledge that groups like al-Qaida and ISIL are deliberately targeting their propaganda to Muslim communities, particularly Muslim youth. And Muslim communities, including scholars and clerics, therefore, have a responsibility to push back.

9. SOUNDBITE (English) Barack Obama, US President:
"The world hears a lot about the terrorists who attacked (French satirical magazine) Charlie Hebdo in Paris. But the world has to also remember the Paris police officer, a Muslim, who died trying to stop it. The world knows about the attack on the Jews at the kosher supermarket in Paris, we need to recall the worker at that market, a Muslim, who hid Jewish customers and saved their lives. And when he was asked why he did it, he said 'we are brothers, it is not a question of Jews or Christians or Muslims'. We are all in the same boat and we have to help each other get out of this crisis."

"We are all in the same boat, we have to help each other. In this work you will have a strong partner in me and the United States of America. Thank you very much. Thank you."
The world has to "confront the warped ideology" of extremists such as al-Qaida and the Islamic State group, US President Barack Obama said on Thursday.
Speaking in Washington, DC, Obama told delegates from 65 countries attending a three-day White House summit: "We are all in the same boat, we have to help each other."
"These terrorists are desperate for legitimacy and all us have a responsibility to refute the notion that groups like ISIL somehow represent Islam, because that is a falsehood that embraces the terrorist narrative," he said.
Obama has sought to use this week's White House summit on violent extremism to urge the world to broaden its response far beyond military interventions.
US airstrikes have managed to blunt some of the militants' gains in Iraq and Syria, but they don't address the extreme ideologies that underpin groups such as the Islamic State group, al-Qaida, al-Shabab and Boko Haram.
The president urged Arab nations in particular to take steps to quell sectarian violence and boost economic and educational opportunities that could provide young people in particular options beyond joining extremist groups.
