Vienna talks on Iran nuclear deal will continue over weekend [VIDEO]

Talks in Vienna to reach an agreement on the Iran nuclear question will continue into the weekend.

As another deadline passed, Britain’s foreign secretary said progress had been “painfully slow.”

Iran’s foreign minister Mohammad Javad Zarif has been trying to hammer out a final deal limiting his country’s nuclear return for sanctions relief.

“Some progress has been made but we are not there yet … I doubt it will happen today … it seems that were are going to spend the weekend in Vienna,” Zarif told reporters.
