Israel Defense Minister Israel Katz on Sunday ordered the military to block an aid boat on its way to Gaza carrying a dozen activists, including Swedish climate campaigner Greta Thunberg.

The almost 20 months of war has torn Gaza apart, often displacing residents multiple times and killing more than 54,000 people, according to the Hamas-run Health Ministry. A U.S.-brokered ceasefire agreed in January collapsed in March as Israel enforced a blockade on all humanitarian aid into the strip.
