Iran has performed the biggest ND maybe ever.
TEHRAN, Iran — A missile fired during an Iranian military training exercise mistakenly struck a naval vessel instead of its intended target in waters near the strategic Strait of Hormuz, killing 19 sailors and wounding 15 others, Iranian authorities said Monday.
The bungled training exercises took place Sunday and raised new questions about the readiness of the Islamic Republic’s armed forces amid heightened tensions with U.S., just months after they accidentally shot down a Ukrainian jetliner near Tehran, killing 176 passengers.
It also comes soon after a tense naval encounter between Iranian and U.S. forces in the nearby Persian Gulf.
In Sunday’s friendly fire incident, a missile struck the Iranian navy vessel Konarak near the port of Jask, some 1,270 kilometers (790 miles) southeast of Tehran in the Gulf of Oman, the Iranian army said in a statement. Iran’s regular navy typically patrols those waters, while vessels from the paramilitary Revolutionary Guard usually patrol the Persian Gulf.
The Konarak, a Hendijan-class support ship taking part in the exercise, came too close to a target and the missile struck it, state TV said. Authorities did not identify the ship that fired the missile, though semiofficial media in Iran identified it as the Iranian destroyer Jamaran.
