Kerry extended his stay in Kabul to try to thrash out a long-delayed security pact that would allow between 5,000 and 10,000 US troops to remain in Afghanistan after 2014 to fight Al-Qaeda remnants and train the national army.
But he said that a major sticking point in efforts to sign the Bilateral Security Agreement (BSA) was the issue of which country would try any US soldiers deployed in Afghanistan.
"We need to say that if the issue cannot be resolved, unfortunately there cannot be a bilateral security agreement."
Karzai said that a national assembly of tribal elders would be called to discuss whether foreign soldiers could be given immunity from prosecution in Afghanistan, as the issue was "above government authority".
"After several months of negotiation, and intense talks yesterday and today, we have reached a series of agreements," Karzai told reporters at a joint press conference in Kabul.
A similar US security agreement with Iraq in 2011 collapsed over the issue of troop immunity.
The US pulled its troops out of the country, which is currently suffering its worst sectarian violence since 2008.
But Afghan officials dismiss the possibility that the US may enact the "zero option" of a complete pull-out after its soldiers have fought the Taliban militants since 2001.
Kerry had been due to fly to Paris today morning, but negotiations ran late into the evening.
The US wants the security deal signed within weeks to enable the NATO military coalition to plan its withdrawal of 87,000 combat troops from Afghanistan by December 2014, but Karzai recently threatened to walk away from talks.
