The U.S. and Russian presidents are urging their nuclear negotiators to step up efforts to complete a new arms control agreement to replace a Cold War-era pact expiring this week.
U.S. National Security Council spokesman Mike Hammer said Tuesday that President Barack Obama and Russian counterpart Dmitry Medvedev raised the issue in a phone call Monday about U.S. plans in Afghanistan.
U.S. and Russian negotiators are trying to finish a replacement agreement for the Strategic Arms Reduction Treaty, which expires Dec. 5th.
The agreement would reduce the two countries nuclear arsenals.
Hammer said that Obama and Medvedev instructed "negotiators to redouble their efforts to resolve outstanding issues."
