Iranian state media shows video of "human chain" lined up in front of a power plant

Iran's official Fars state news agency posted a short video on social media Tuesday showing what it said was a "Human chain in front of the Kazerun combined cycle power plant."

The video seemingly showed hundreds of people who had answered a call by an Iranian government official for civilians to act as human shields in front of the country's power plants.

President Trump has warned Iran's rulers that if they don't reopen the Strait of Hormuz to all shipping traffic by 8 p.m. Eastern, he will order strikes to destroy all of the country's power plants and bridges.

Multiple online resources describe the Kazerun (or Kazeroon) power plant as a natural gas-fired production facility in Iran's southwest Fars province, which is near the Persian Gulf.
