President Trump says he wants "a real end" to Iran's nuclear problem, with Tehran abandoning it "entirely," and not just a ceasefire between Iran and Israel.

Tehran is one of the largest cities in the Middle East, with around 10 million people, roughly equivalent to the entire population of Israel.

The head of the International Atomic Energy Agency says there is a possibility of both radiological and chemical contamination within Iran’s main nuclear enrichment facility in Natanz.

President Donald Trump in about eight hours went from suggesting a nuclear deal remained “achievable” to urging Tehran’s 9.5 million residents to flee for their lives

After canceling negotiations with the U.S. scheduled for Sunday, Tehran has signaled it is willing to talk.

The Israeli military struck "over 170 targets" in Iran in three days, the Israel Defense Forces (IDF) said on Sunday.

Smoke and flames filled the sky over Tehran as Israel struck oil and gas facilities in the Iranian capital and targeted more nuclear facilities during attacks that carried on into Sunday after starting two days earlier.

The Israeli military has damaged critical nuclear infrastructure and killed scientists, but Tehran’s most formidable enrichment plant remains.
