Negotiators in Lausanne, Switzerland, continue to meet over an Iran nuclear deal after extending the talks for another day. In Washington, White House Press Secretary Josh Earnest said enough progress was made to continue negotiations past the U.S.-imposed Tuesday deadline.

White House Press Secretary Josh Earnest: “It also doesn’t make sense, if we are getting serious engagement from the other side, to just abruptly end the talks based on this — based on this deadline, because the fact is, if we are making progress toward the finish line, then we should keep going.”

Russia says “key aspects” of a general agreement have been reached, to be finalized in a new phase aimed at a comprehensive agreement in June. But other sources have denied any deal has been struck. Details of the talks have been kept under wraps.
