Senior U.S. military commanders on Wednesday accused Iran’s military of “highly provocative” actions in firing unguided rockets 1,500 yards from ships including an American aircraft carrier.

The USS Harry S. Truman was crossing international waters in the Strait of Hormuz when Iranian Revolutionary Guards (IRCGN) conducted a live-fire exercise right nearby, according to a statement.

An Iranian navy attack craft fired several unguided rockets near the carrier, officials said. A French frigate, the U.S. destroyer USS Bulkeley and other commercial traffic were also in the area at the time of Saturday’s incident.

Only 23 seconds warning was given before the weapons were fired, according to U.S. Navy Cmdr. Kyle Raines, a spokesman for U.S. Central Command ….

“The IRGCN’s actions were highly provocative,” Cmdr. Kevin Stephens, spokesman for the U.S. Fifth Fleet, said Wednesday in a statement.

“Firing weapons so close to passing coalition ships and commercial traffic within an internationally recognized maritime traffic lane is unsafe, unprofessional, and inconsistent with international maritime law.”

Of course, Iranian news sources say that the exercises were announced in advance and that no ships were in danger, but the U.S. Navy says that the ships were in international waters.

The Harry S. Truman is now in the Arabian Gulf, and launching airstrikes against Islamic State terrorists, joining the French aircraft carrier FS Charles De Gaulle for combined combat operations in Iraq and Syria.
