Thirteen are dead and more than 250 injured after a chlorine tank crashed onto the deck of a ship and leaked toxic gas at Jordan’s Aqaba port.

The unidentified ship was loading at the port when a tank fell from a crane, sending a plume of yellow smoke in all directions and port employees scrambling, video posted to social media shows.

According to multiple media reports, authorities are calling on residents to shut their windows and stay indoors.
