It is more than 23 years since Arab countries last made common cause to join U.S.-led military action, and it has taken the threat of Islamic State to persuade them that any public backlash in an already turbulent region is a price worth paying.

Islamic State militants fighting in Iraq and Syria released a video on Tuesday that appears to show British journalist John Cantlie criticizing preparations for U.S-led attacks on the militant group, the SITE monitoring service reported.

President Barack Obama wants some Arab participation in air strikes against the Islamic State in order to expand the campaign to Syria, reflecting U.S. concerns that any long-term campaign must count on regional involvement, U.S. officials say.
