Russia has joined Iran in suggesting that a late November deadline for reaching an agreement to end a long-running dispute over Tehran's nuclear program may need to be extended.

U.S. Secretary of State John Kerry and Russian Foreign Minister Sergei Lavrov agreed on Tuesday to increase intelligence sharing between Moscow and Washington on Islamic State militants, focusing on a common enemy even as deep divisions remained over the crisis in Ukraine.

The threat from Islamic State fighters to the Syrian Kurdish town of Kobani is an early test of the U.S.-led coalition's patience for a military strategy that at the moment cannot hold ground in Syria.
