Lausanne, SWITZERLAND—Iranian Foreign Minister Javad Zarif and European Union foreign policy chief Federica Mogherini will give a joint news statement later Thursday in Lausanne, on the eighth day of the latest round of nuclear talks, a diplomat involved in the talks said.

“Talks have progressed,” the person said.

Ministers are still holding discussions, a second western official said.

In Washington, President Barack Obama delayed his departure for a planned trip to Kentucky and remained at the White House as negotiators prepared to deliver statements. He was initially scheduled to leave for Kentucky at 12:20 p.m. EDT.

White House press secretary Josh Earnest said on Wednesday that once negotiations reached a conclusion Mr. Obama would address the result in public remarks. Mr. Obama, who has spoken publicly at key moments in negotiations, is expected to do so on Thursday.

A deadline for a political understanding on the main outlines of a final nuclear deal passed on Tuesday, but US Secretary of State John Kerry and most of his counterparts from a group of six world powers stayed on to continue talks with Mr Zarif through Thursday.

The two sides are aiming to seal a final nuclear deal by June 30 which would block Iran’s path to a nuclear weapon in return for lifting international sanctions on Tehran.
