New Delhi (CNN) The military option is out, President Barack Obama said Sunday, but the U.S. will be looking at all other options to "ratchet up the pressure on Russia" on the issue of Ukraine.

Speaking in New Delhi after a lengthy flight on Air Force One, Obama said Sunday he will "look at all the additional options that are available to us short of military confrontation."
