An Iran deal 'over' and war back on? A timeline of the conflict and talks

An Iran deal 'over' and war back on? A timeline of the conflict and talks traces how U.S.-Iran negotiations deteriorated amid renewed strikes and market volatility tied to energy shipping risk. Following further attacks between the United States and Iran, President Donald Trump suggested the fragile talks might be “over,” with stakes described as including people across the region, Israel and Lebanon, Gulf-area residents, U.S. military personnel in multiple countries, and thousands of mariners trying to exit the Strait of Hormuz. The timeline begins with Feb. 28, when Israel and the U.S. attacked Iran, killing Supreme Leader Ayatollah Ali Khamenei and other top officials; Iran then struck Israel and asserted control of the strait. It covers Hezbollah joining March 2, a naming of Mojtaba Khamenei as new supreme leader on March 8, and a two-week ceasefire starting April 7 before U.S.-Iran talks ended April 12 in Pakistan’s capital. Later developments include a U.S. blockade move April 13, multiple Lebanon-Israel diplomatic efforts in Washington, an interim uranium deal signed June 17, and repeated ceasefire renewals and breakdowns through late June.
