'Afghan, pak pose security threat to US''
Afghanistan and Pakistan pose a major security threat to the United States, where Al-Qaeda and its affiliate terrorist groups are seeking to regain territorial control, President Barack Obama's nominee to be ambassador to Kabul said on Thurday.
Secretary of State Hillary Clinton said the entire situation in Pakistan is ``a concern'' and warned that extremists there posed a direct threat to the country as well as to the security of US, Afghanistan and a number of other nations in and outside the region.
