Lausanne, Switzerland (CNN)Talks to reach a deal on a framework agreement on Iran’s nuclear program will be extended an extra day, U.S. officials said Tuesday.
“We’ve made enough progress in the last days to merit staying until Wednesday. There are several difficult issues still remaining,” State Department spokeswoman Marie Harf said.
White House press secretary Josh Earnest said the talks in Lausanne would continue another day as “long as the conversations continue to be productive.”
Diplomats and negotiators worked late as an initial deadline approached, but more time appeared necessary to reach a framework deal.
How long talks will continue was unclear. French Foreign Minister Laurent Fabius informed the Iranians that he will return to Paris at dawn Wednesday in an apparent effort to force the Iranians’ hand, Western diplomatic sources told CNN.
