Iran's supreme leader seeks to avert a U.S. attack after crushing protests

Ayatollah Ali Khamenei ordered a severe security crackdown on nationwide protests that activists say killed thousands, and he has allowed nuclear talks with the United States as tensions rise with an American flotilla nearby.

Ayatollah Ali Khamenei moved to suppress widespread protests in January with a severe security crackdown. Activists report thousands killed and many detained, while officials give a lower death toll. With a U.S. naval presence reported nearby, Khamenei has warned that U.S. strikes could spark wider conflict and has allowed Iran to enter negotiations with the United States over its nuclear program. Economic hardship, sanctions and long-standing political tensions have been cited as drivers of the unrest. Key points: - Activists report more than 6,700 people killed and tens of thousands detained during the recent crackdown; the Iranian government has reported 3,117 deaths. - A U.S. naval flotilla is reported nearby; Khamenei has warned that strikes could lead to a regional war and has permitted talks with the U.S. on the nuclear file. - Officials and mediating states say talks could take place in the coming days, but the two sides remain far apart on core demands such as halting enrichment and surrendering uranium stocks. Summary: The crackdown has heightened internal strain on Iran's theocratic system and underscored the influence of the Revolutionary Guard. Khamenei's engagement in nuclear negotiations appears aimed at reducing the immediate risk of military action. Talks may occur in the coming days, but major differences remain and the outcome is undetermined at this time.
