JERUSALEM >> Israeli warplanes bombed ports and a power plant in Yemeni territory controlled by the Houthis on Friday, the Israeli military said, in the latest attempt to force the Iranian-backed militant group to stop firing at Israel and commercial ships in the Red Sea.

Israel has escalated its strikes on the Houthis in recent weeks in response to repeated attacks by the Yemeni militia, which has been launching missiles and drones against Israel in solidarity with Hamas in the Gaza Strip. The United States and Britain have also struck Yemen repeatedly in an effort to secure international waterways from Houthi attacks, including new U.S. strikes Wednesday.

But it was far from clear whether Israel and its allies could successfully compel the Houthis to end their attacks on Israel and on ships through a bombing campaign. Months of Israeli and U.S. airstrikes have failed to deter the well-equipped militia from conducting attacks.

The Israeli military said it had bombed the Hezyaz power station near Sanaa, Yemen — the Houthi-controlled capital — and the Red Sea ports of Hodeida and Ras Isa. The power station is not far from where thousands of Yemenis had gathered in a weekly rally in solidarity with Palestinians, and Ras Isa is Yemen’s main oil export terminal.

Experts have warned that attacking ports like Hodeida, a major conduit for essential supplies in northern Yemen, could further worsen what is already one of the world’s worst humanitarian crises. Rocked by civil war for more than a decade, millions of people in Yemen face the threat of malnutrition, according to the United Nations.

The Israeli military said it had struck targets at sites that were being used by the Houthis for military purposes. More than 20 aircraft took part in the operation, which required in-flight refueling, and dropped about 50 munitions, said an military official, who briefed reporters on condition of anonymity in accordance with military protocol.

One worker at the Hezyaz power station was wounded, according to al-Masira, the Houthi-affiliated broadcaster. There were no other immediate reports of serious casualties.

“The port of Hodeida is paralyzed and the port of Ras Isa is ablaze,” Israel Katz, the Israeli defense minister, said in a statement. “The message is clear: Anyone who harms Israel will be struck tenfold.”

The Houthis, who control much of western Yemen, are more than 1,000 miles from Israeli territory and have survived numerous efforts to defeat them since they rose to power in a civil war that began in 2014. The United States designates the Houthis as a terrorist group, and Saudi Arabia and the United Arab Emirates, U.S. allies in the region, intervened in the civil war to fight against the Houthis.On Friday, Katz threatened to kill Abdul-Malik al-Houthi, the group’s leader, as well as its other commanders.
