South Korea (searchwill not backtrack on plans to send 3,600 troops to Iraq or follow Spain's (searchfootsteps by threatening a pull out, a senior official said Friday.

South Korea became the latest U.S. ally in Iraq to re-examine sending troops to an increasingly violent peacekeeping effort last week, when it scrubbed plans for a mission to the Iraqi hotspot of Kirkuk (search).

South Korea has promised to eventually dispatch the 3,600 troops earmarked for Iraq, but only after it finds a location where they won't have to perform offensive missions. The Kirkuk decision came after Spain announced it may pull out its troops in the wake of deadly train bombings and Poland said it was "misled" about the U.S.-led war.

"One of our concerns is that by changing the location, we may give the wrong impression to the public and friends that South Korea may backtrack on the commitment," the senior government official said on condition of anonymity.

"We have to make clear we are not moving in that direction. We will abide by our commitment," he said. "Some people harbor the notion that South Korea might be following the suit of Spain. That's completely untrue."

The troops, to include special forces and marines, were to take complete control of relief and security needs in the region around Kirkuk, some 180 miles north of Baghdad.

But the plans were scrapped because the U.S. military wanted to keep a contingent in the area under South Korean command that would continue raids and other offensive missions. That would be contrary to a South Korean parliamentary mandate restricting the troops to peacekeeping and reconstruction efforts.

The United States is preparing several alternative locations for South Korean troops, and Seoul will review them before making a decision, the official said. Najaf, the southern Iraqi town where Spanish troops currently operate, is one possibility, but the official declined to name other potential locations.

The new selection process will push back the planned April dispatch. The official would not say how long the delay would be, but denied domestic politics was playing into the decision.

President Roh Moo-hyun, who supports the deployment, was impeached for unrelated reasons earlier this month, and the nation faces nationwide elections April 15. Some had speculated that any casualties sustained by South Korean troops before the polls could tip the outcome. Others have suggested that a major upheaval in the National Assembly's makeup could impact its backing for a mission that is unpopular with the South Korean public.

Sending 3,600 troops would make South Korea the biggest coalition partner after the United States and Britain. About 460 South Korean medics and military engineers have been in the southern Iraqi town of Nasiriyah for almost a year and will come home when the new dispatch is made.
