The two-week ceasefire was announced after weeks of fighting that began on February 28 when the United States and Israel launched strikes on Iran while negotiations were still underway.

President Trump said on Wednesday that Washington would work closely with Iran following what he described as a “productive regime change,” adding there would be no uranium enrichment.

But messages from across Iran suggested the pause in fighting has stirred mixed and often painful reactions. Some described the truce as a missed opportunity for political change.
