Iranian authorities held mass public weddings in Tehran for couples who signed up to a state-sponsored scheme declaring their readiness to sacrifice their lives in the war against the US and Israel.

The ceremonies conducted late on Monday involved hundreds of couples in several major squares in the capital, including more than 100 in the vast Imam Hossein Square in central Tehran, according to reports in Iranian media.

They were broadcast on state TV in a bid to boost wartime morale, with US President Donald Trump repeatedly threatening new military action against Iran amid a shaky ceasefire which halted the fighting that began on February 28.

Those involved had signed up, according to Iranian media, for the “self-sacrifice” scheme (janfada in Persian) where people pledged to put their lives on the line in the war by, for example, forming human chains outside power stations.

Iranian authorities say millions of people, including top figures such as speaker of parliament Mohammad Bagher Ghalibaf and President Masoud Pezeshkian, have put their names forward.
