Secretary of State John Kerry said the United States will use a NATO summit next week to push for a coalition of countries to beat back incursions in Syria and Iraq by Islamic State militants who are destabilizing the region and beyond. "With a united response led by the United States and the broadest possible coalition of nations, the cancer of ISIS will not be allowed to spread to other countries," Kerry wrote in an opinion piece published in The New York Times on Saturday. Public anger over the beheading of American journalist James Foley has led President Barack Obama to consider military strikes against Islamic State targets in Syria. So far, the United States has limited its actions to the group's forces in Iraq.
By Adrian Croft and Jan Strupczewski BRUSSELS (Reuters) - European Union leaders will threaten Russia with new sanctions over Ukraine on Saturday but, fearful of a new Cold War and self-inflicted harm to their own economies, should give Moscow another chance to make peace. At a summit in Brussels that handed one of the Union's top jobs to Poland's premier and gives hawkish Kremlin critics in Eastern Europe new influence in the bloc, EU officials gave Ukraine's embattled President Petro Poroshenko a warm welcome and assurances of further economic and other support.
