Israel says its military has attacked Houthi targets at three ports and a power plant in Yemen.
Defence minister Israel Katz confirmed the strikes, saying they were carried out due to repeated attacks on Israel.
Mr Katz said the Israeli military attacked the Galaxy Leader ship which he claimed was hijacked by the Houthis and was being used for “terrorist activities in the Red Sea”.
It came after the Israel Defence Forces (IDF) issued an evacuation warning for people at Hodeidah, Ras Issa, and Salif ports – as well as the Ras al Khatib power station, which it said is controlled by Houthi rebels.
The IDF said it would carry out airstrikes on those areas due to “military activities being carried out there”.
An IDF spokesperson said: “For your safety, we urge all those present in the specified areas, as well as ships anchored nearby, to evacuate immediately. Remaining in the specified areas puts you in danger.”
Afterwards, Mr Katz confirmed the strikes at the ports and power plant.

Earlier in the day, a ship was reportedly set on fire after being attacked in the Red Sea.
A private security company said the assault, off the southwest coast of Yemen, resembled that of the Houthi militant group, which is backed by Iran.
It was the first such incident reported in the vital shipping corridor since mid-April.
The vessel, identified as the Liberian-flagged, Greek-owned bulk carrier Magic Seas, had taken on water after being hit by sea drones, maritime security sources said.
The crew later abandoned the ship.
A renewed Houthi campaign against shipping could again draw in US and Western forces to the area, particularly after President Donald Trump targeted the rebels in a major airstrike campaign.
The ship attack comes at a sensitive moment in the Middle East.
A possible ceasefire in the Israel-Hamas war hangs in the balance and Iran is weighing up whether to restart negotiations over its nuclear programme.
It follows American airstrikes last month, which targeted its most-sensitive atomic sites amid an Israeli war against the Islamic Republic that ended after 12 days.
