European officials urged Iran to restrict its nuclear program to prevent the U.S. from joining Israel’s attacks but President Donald Trump called the meeting unhelpful.

A meeting between Iran’s foreign minister and senior European diplomats has yielded hopes of further talks but no indication of any immediate concrete breakthrough, a week after the crisis centered on the Iranian nuclear program erupted into war between Israel and Tehran.

Israel and Iran pummeled each other with airstrikes for the eighth consecutive day today, even as European diplomats met with an Iranian delegation in an effort to cool the conflict. Those talks ended with no signs of a breakthrough.
