President Obama is warning Iran that the window for a diplomatic resolution to the standoff over Iran’s alleged nuclear activities is “shrinking.” Obama made the comment during a news conference with British Prime Minister David Cameron.

President Obama: “In the past, there has been a tendency for Iran in these negotiations with the P5-plus-1 to delay, to stall, to do a lot of talking but not actually move the ball forward. I think they should understand that because the international community has applied so many sanctions, because we have employed so many of the options that are available to us to persuade Iran to take a different course, that the window for solving this issue diplomatically is shrinking.”
