NATO Secretary General Anders Fogh Rasmussen on Tuesday said that he is confident Pakistan's nuclear arsenal is safe and well-protected. However, Mr. Rasmussen said it is still a matter of concern, and that NATO will continue to closely monitor the situation. His comments came after a meeting in Kabul with Afghan President Hamid Karzai. They discussed security issues and the process of handing over control of some parts of Afghanistan, which is scheduled to begin in July. Afghan security forces are set to take increasing responsibility for security as coalition forces withdraw from the country, which is not due to be completed until 2014.
