The U.S. launched strikes against Iran in response to drone attacks on a ship in the Strait of Hormuz yesterday, U.S. Central Command said. President Donald Trump called Iran’s action a violation of the ceasefire agreement.

A U.S. aircraft struck Iranian missile and drone storage locations as well as coastal radar sites, according to CENTCOM.

The ceasefire agreement signed last week stipulated that the strait would reopen and that Iran agreed to allow safe passage of commercial vessels with no charge for 60 days
