Secretary of State John Kerry said Friday that the U.S. and Russia have some "clarity" on the path they need to take to reach a new Syria ceasefire agreement, and indicated a deal might be reached in the coming days.

The Associated Press reported that Kerry said "narrow issues" still need to be resolved, after nearly 10 hours of meetings with Russian Foreign Minister Sergey Lavrov.

The U.S. and Russia have been working for weeks on a way forward to reduce the violence in Syria's civil war, which has been difficult given the opposite sides the two countries have taken in the conflict.

The Obama administration has said Russia never stopped bombing some of the moderate Syrian opposition groups that the U.S. has been trying to help. U.S. officials have also said Russia's actions overall are not consistent with the ceasefire that several countries tried to impose months ago.

In August, Kerry had few answers for what to do about Russia's actions, which prevented Syria from starting political talks to end the civil war on Aug. 1, a deadline supported by the U.S.

"It is critical, obviously, that Russia restrain both itself and the [Bashar] Assad regime from conducting offensive operations, just as it is our responsibility to get the opposition to refrain from engaging in those operations," Kerry said.

In late July, Kerry said he was hoping for an August breakthrough on some kind of joint U.S.-Russia military cooperation in Syria, but that hasn't happened yet.
