The Israeli Air Force launched airstrikes Sunday against infrastructure in western Yemen that the military said was used by the Houthis, in a response to recent ballistic missile attacks on the Jewish state carried out by the Iran-backed group.

It was only the second-ever Israeli strike in Yemen, after in July, the IAF conducted an attack on Yemen’s Hodeidah port after a drone hit Tel Aviv, killing a man in his apartment.

Four people were killed and 29 wounded in the attack, the Houthi-run health ministry said in a statement.
