Israel seeks genuine efforts on Iran's nuclear capabilities from Friday's meeting between European and Iranian ministers, not just another round of talks, Israel's UN ambassador said.

"We have seen diplomatic talks for the last few decades, and look at the results," Danny Danon told reporters at the United Nations.

"If there will be genuine effort to dismantle the capabilities of Iran, then that's something we can consider, but if it is going to be like another session and debates, that's not going to work.

"If it is going to be just another round of talks, that's something which we cannot accept," Danon said.
