In Dezful (southwest), students formed a human chain over the city's historic bridge, which is over 1,700 years old, to defend against Trump's threats. Iran calls on youth to form human chains following Trump's attack threats. These actions are part of a government campaign that called on the country's youth to form human chains this Tuesday to 'stage a symbol of unity and resistance against the enemy,' said this morning the Deputy Minister of Youth Affairs of the Ministry of Sports, Alireza Rahimi. Rahimi indicated that 'the youth of Iran, with any ideology or preference, will unite to tell the world that attacking public infrastructure is a war crime'. Figures of Iranian culture, including Iranian musician Ali Gamsari and singer Benyamin Bahadori, began setting up near power plants and bridges yesterday in response to Trump's threats to 'unleash hell' if Tehran does not reopen the Strait of Hormuz before 8:00 PM on Tuesday in Washington. Tehran has blocked the transit of ships through the Strait of Hormuz since the beginning of the war, through which 20% of the world's oil passes, and only allows passage to ships from countries it considers allies, which has driven up the price of oil, among other products. On Tuesday, April 7, thousands of people formed human chains in front of power plants and bridges in various Iranian cities to protest against the threats of attacks from US President Donald Trump, who warned that he would attack that infrastructure if Tehran does not reopen the Strait of Hormuz. In Tehran, hundreds of people gathered at Iran's largest power plant, Damavand, carrying Iranian flags and condemned US threats to attack vital infrastructure, according to images broadcast by Iranian state television. In the western city of Kermanshah, a group of protesters gathered at the Bisotun power plant, where they carried photographs of the late Supreme Leader Ali Khamenei and his successor and son Mojtaba Khamenei, denouncing that attacking electrical infrastructure constitutes a war crime, as reported by Mehr agency. Human chains were also formed at the thermal power plant in the northwestern city of Tabriz and the Shahid Rajaei power plant in the northern city of Qazvin. The mobilizations were replicated in other parts of the country.
