According to the report, traffic in the canal was halted for several hours in order to allow US Navy vessels, which included an aircraft carrier and carried infantry troops, armored vehicles and ammunition, to pass from the Mediterranean Sea to the Red Sea.

It was further reported that eyewitnesses detected an Israeli warship among the vessels. No confirmation has been received from Egyptian authorities.
