If Trump blocks Israel from attacking Tehran's nuclear sites without resolving the threat, Jerusalem will miss a rare opportunity to eliminate the Iranian nuclear threat.

Iran has long maintained that its nuclear programme is for civilian purposes only. It has several facilities around Iran, at least some of which have been targeted in the Israeli strikes.

The United States and Israel are seeking to turn nuclear talks into a "strategic trap" for Iran, Iranian lawmakers said in a statement on Tuesday, days before a planned sixth round of Iran-U.S. nuclear talks.

The outline of the U.S. offer to Iran in their high-stakes negotiations over Tehran’s nuclear program is starting to become clearer.

Iran has warned it will ramp up its nuclear activities after the United Nations nuclear watchdog’s 35-member board of governors adopted a resolution Thursday declaring it in breach of its non-proliferation obligations.

President Donald Trump warned in a recent interview that he is "less confident" that the United States will reach a nuclear deal with Iran.

A source familiar with the details told the Post there is "definitely a chance" that a sixth round of nuclear talks between the United States and Iran will not take place.

The US and Iran have been negotiating a nuclear deal for around two months, with Oman mediating. They have held five rounds of talks.
