Baghdad ? Iraq’s parliament ended weeks of debate Sunday and passed a long-delayed law paving the way for the planned January election to go forward, sidestepping a crisis that could have delayed the U.S. troop withdrawal.

The decision appeared to resolve a key sticking point — who will be allowed to vote in the disputed, oil-rich city of Kirkuk. The issue had threatened to delay Iraq’s key parliamentary elections, which in turn would affect how quickly American combat forces could leave the country.

U.S. Ambassador Christopher Hill could be seen shuttling between various political factions before the law’s passage. President Barack Obama, speaking at the White House, welcomed the new legislation.
