Israeli Prime Minister Benjamin Netanyahu has warned world powers over what he described as "their retreat from the red lines they had set in their nuclear talks with Iran," saying there is no reason to rush into a final deal with Tehran.

"We are now witnessing a stark retreat from the red lines that the world powers set themselves only recently and publicly," Netanyahu told ministers at the weekly cabinet meeting on Sunday.

He expressed concern that the global powers are giving increasing concessions to Iran over its nuclear program, claiming that a final deal was "getting worse by the day."

Netanyahu�s remarks came as nuclear talks between Iran and the P5+1 countries � the United States, France, Britain, Russia and China plus Germany � continued in the Austrian capital of Vienna on Sunday, two days ahead of a self-imposed deadline.

Iran�s Foreign Minister Mohammad Javad Zarif and US Secretary of State John Kerry met Sunday morning for a third time in 24 hours.

The Iranian foreign minister on Sunday held separate talks with British Foreign Secretary Philip Hammond and his German counterpart Frank-Walter Steinmeier in Vienna. Zarif also met with Chinese Deputy Foreign Minister Li Baodong.

Zarif is scheduled to leave the nuclear talks in Vienna and return to Iran later on Sunday. After a day-long stay in Tehran, he will rejoin the Vienna negotiations.

Nuclear negotiations between Iran and the P5+1 in Vienna seem to miss the June 30 deadline but only by a few days as negotiators say they need more time to settle the remaining differences. However, there is no discussion on a long-term extension of the talks at the moment.

Iran and the five permanent members of the P5+1 group are holding talks to finalize the text of a possible deal over Iran�s nuclear program by the end of June.

The two sides reached mutual understanding on the key parameters of the potential deal in Lausanne on April 2.
