Considered one of the most violent pogroms in Jewish history, the Iași pogrom started on 27 June 1941 and lasted for three days, resulting in an estimated number of 13,000-15,000 Jews killed. The pogrom was conducted mostly by the local police, following an order given by Ion Antonescu. Apart from thousands of Jews being shot at the local police station, other thousands were put into death trains. Most of them would die because of dehydration and suffocation inside those trains.
