A man walks past a placard bearing a message in Persian that reads "Your fire will forever be in our hearts", referring to the death of Iran's late supreme leader Ayatollah Ali Khamenei, at Enghelab Square in central Tehran on August 3, 2026. Iran denied any negotiations were taking place with the United States after the US president said new talks would begin on August 3 in an effort to end their war, now in its sixth month. Washington and Tehran have been at war since February 28, when the US and Israel launched surprise strikes against Iran, though months of on-off diplomacy have led to periods of relative calm.
