The Obama administration said late Wednesday it is still reviewing its policy on a treaty banning anti-personnel landmines, clarifying a previous statement indicating it would not sign the deal. "The administration is committed to a comprehensive review of its landmine policy. That review is still on-going," State Department spokesman Ian Kelly said in a statement on Wednesday. "The review is going to take some time, given that it is the first review of our policy conducted since 2003," Kelly added.
