US President Donald Trump is considering whether to join Israel's strikes on Iran's nuclear sites, as the conflict continues for a sixth day and angry rhetoric ramps up between all sides.
American strikes could involve using superior weaponry to hit an underground nuclear site at Fordo, according to five sources who spoke to the BBC's US partner CBS News.
The president met with his national security team on Tuesday to discuss next steps.
Israel and Iran have exchanged deadly strikes since Friday. Analysts say Trump's comments suggests a willingness to join the Israelis, despite his earlier call for de-escalation and his vocal support for a diplomatic solution to limit Iran's nuclear research.
He has shown increasing frustration over a perceived lack of progress to secure a new deal that would be aimed at preventing Iran from building a nuclear weapon. Trump pulled out of a previous accord with Iran during his first term.
