Kabul, Afghanistan (CNN) -- The Afghan president met with a top U.S. senator Tuesday and asked for a review of Washington's Afghanistan war strategy, the president's office said in a statement.
President Hamid Karzai discussed the issue with Sen. John Kerry, the Massachusetts Democrat who is the chairman of the Senate Foreign Relations Committee.
Karzai spoke about the letter he sent to U.S. President Barak Obama about the review of war strategy and fighting terrorism.
Karzai said that the war won't be successful until there's "a clear explanation of who is friend and who is foe and until we focus on the bases and roots" of terror.
"This is why there is a need for reviewing the goals and strategy of war," Karzai said.
Participants in the meeting included Dr. Rangin Spanta, Afghanistan's national security adviser; U.S. Ambassador to Afghanistan Karl Eikenberry and Gen. David Petraeus, the top international military official in the country.
Karzai told officials that they should avoid actions that disturb Afghans and discussed his plans to shut down private security firms.
