Dockworkers in 22 countries went on strike on Friday against the war and the use of ports for arms exports, an action organizers say could disrupt more than 40% of Mediterranean cargo and over $2 billion worth of freight, according to Reuters.

The strike was originally called by unions in Italy, France, Greece, Spain's Basque Country, Turkey and Morocco and now has the backing of more than 25 unions in 113 ports. Protesters at more than 100 ports in 22 countries called on dock workers to disrupt arms shipments to Israel, according to Middle East Eye.
