NEWTON, Mass. (AP) - Sen. John Kerry says he believes there is a "way forward" to resolving a delicate dispute with Pakistan over the arrest of a U.S. Embassy employee who shot to death two Pakistani men he claims were trying to rob him.

Kerry, a Massachusetts Democrat and the Senate Foreign Relations Committee chairman, traveled to Pakistan this week at the request of President Barack Obama. Kerry says there are still "very difficult" legal issues to deal with in the case of Raymond Allen Davis.

Kerry says he discussed his trip and options for resolving the situation with Secretary of State Hillary Clinton on Friday. He did not elaborate.

The U.S. has called for the release of Davis, saying he acted in self-defense in the Jan. 27 shootings and qualifies for diplomatic immunity.
