“This is only the latest in the series of attacks instigated by the Republic of Iran and its surrogates against American allies and interests. They should be understood in the context of four years of unprovoked aggression against freedom-loving nations,” Pompeo said.

Earlier on Thursday, two oil tankers, identified as Marshall Islands-flagged Front Altair and the Panama-flagged Kokuka Courageous, were rocked by explosions in the Gulf of Oman. There’s so far little information on what actually happened, but one of the vessels was reportedly hit by a torpedo. Iran said it had rescued 44 sailors from the distressed tankers and called the incident “suspicious.”
