U.S. President Barack Obama on Tuesday paid a surprise visit to Afghanistan and signed an agreement on cooperation with the Central Asian country's leader Hamid Karzai, CNN reported.
"Afghanistan has a friend and a partner in the United States," Obama said prior to signing, jointly with Karzai, the Strategic Partnership Agreement outlining interaction between the countries after the withdrawal of the U.S.-led international troops in 2014.
Obama also thanked U.S. troops for their service on the first anniversary of a United States raid killing Osama bin Laden in neighboring Pakistan.
