Islamic State

A checkpoint near Kirkuk marks the line between Kurdish-controlled territory and the world of Islamic State extremists. Some 5,000 civilians stream across daily, lives and families divided.

Turkey's deep suspicions of Kurds are hampering efforts to aid the besieged Syrian border town. Turkish authorities are stopping Kurdish men en route to Kobani and investigating them as terrorists.

In an interview with NPR, Israeli Prime Minister Benjamin Netanyahu says that Arab countries "no longer view Israel as an enemy but a potential partner."

Thousands of international recruits have crossed into Syria from Turkey to join the Islamic State. A Syrian man who helped smuggle those jihadis in explains how it worked, but says he's stopped now.
