President Trump is pressuring Iran to either curtail its nuclear program or face military strikes, after Iran amassed a large stockpile of highly enriched uranium. Here's what to know.

'I guess I am considering that,' President Donald Trump said of as he weighed a limited strike on Iran amid nuclear negotiations.

The US could allow Iran to continue with “token” nuclear enrichment if it leaves itself no path to an atomic bomb, according to reports.

The head of the U.N. nuclear watchdog agency says Iran's enriched uranium "is still there," as he stresses the urgency of diplomacy to avert a U.S.-Iran war.

Trump said the world would know in 10 or 15 days whether Iran would reach a deal to avoid military action over its nuclear program.
