The Washington Post reports:
Several cruise missiles fired from Russian ships at targets in Syria Wednesday crashed in Iran, according to Pentagon officials.
Twenty-six cruise missiles, launched from the Caspian Sea, traveled more than 900 miles over Iran and Iraq before hitting targets throughout Syria, according to a statement by the Russian Defense Ministry.
However, according to a senior U.S. defense official who requested anonymity to discuss intelligence matters Thursday, a few of the missiles did not make it to their intended targets.
Reports on Iranian TV indicated that an “unidentified flying object” had crashed and exploded in a village near near the Iranian city of Takab. A number of cows were killed in the ensuing blast.
While it is unclear what made the missiles crash, videos posted on social media showed them flying overhead at low altitude. While it is common for cruise missiles to fly low (to avoid radar detection), it can make traversing mountainous terrain perilous.
