JERUSALEM  — Israel's prime minister is urging the international community to step up the pressure on Iran, despite some optimism following the latest round of nuclear talks with the Islamic Republic.

Benjamin Netanyahu told his Cabinet on Sunday that "as long as we don't see actions instead of words, the international pressure should continue, and even more than that, it should be strengthened."

It was Netanyahu's first public statement on last week's round of talks between Iran and global powers over its suspect nuclear program. Negotiators ended the talks on an upbeat note, though they gave no details on what proposals were exchanged.

U.S. officials say the White House is debating whether to offer Iran the chance to recoup billions of dollars in frozen assets if it scales back its nuclear program.
