U.S. Secretary of State Marco Rubio has defended Washington’s blockade enforcement operations in the Strait of Hormuz after India lodged a formal protest over attacks that killed three Indian mariners aboard a commercial tanker this week. According to a State Department readout released Friday, Rubio discussed the situation during a call with Indian External Affairs Minister S. Jaishankar, stressing that commercial vessels operating in the region must comply with instructions from U.S. forces.
