For the first time, Yemen's Houthis publicly announced they targeted Israel in coordination with Iran.
Spokesperson Yehya Sareagroup said the group targeted central Israel's Jaffa with several ballistic missiles in the past 24 hours.
"Triumphing for the oppressed Palestinian and Iranian peoples... this operation was coordinated with the operations carried out by the Iranian army against the criminal Israeli enemy," he added.
Meanwhile, Israeli media reported last night the military attempted to assassinate a senior Houthi leader.
For context: The Houthis are part of an Iran-aligned regional alliance, which also includes Hamas and Lebanon's Hezbollah.
The group governs swathes of Yemen, including the capital Sanaa, more than a thousand miles from Israel.
It has blamed Israel for instability in the Middle East, saying the "circle of conflict" in the region was driven by its "continued crimes".
The group seized Sanaa and much of the country's north in 2014.
In January 2015, they surrounded the residence of former president Abd Rabbu Mansour Hadi, forcing him to flee.
