ARBIL, Iraq/MURSITPINAR, Turkey - Iraqi Kurdish troops drove Islamic State fighters from a strategic border crossing with Syria on Tuesday and won the support of members of a major Sunni tribe, in one of the biggest successes since US forces began bombing the Islamists.
The victory, which could make it harder for militants to operate on both sides of the frontier, was also achieved with help from Kurds from the Syrian side of the frontier, a new sign of cooperation across the border.
Iraqi Kurdish Peshmerga fighters took control of the Rabia border crossing in a battle that began before dawn, an Iraqi Kurdish political source said.
"It's the most important strategic point for crossing," the source said.
The participation of Sunni tribal fighters in the battle against Islamic State could prove as important a development as the advance itself.
