JERUSALEM — Israel’s military on Tuesday launched airstrikes against Iranian-backed Houthi rebels in Yemen that it said fully disabled the international airport in the Yemeni capital, Sanaa.

The strikes came hours before U.S. President Donald Trump said the United States would stop striking the Houthis, who he said had “capitulated” and agreed to stop targeting shipping in the Red Sea. The U.S. military under Trump separately had launched an intensified campaign of airstrikes targeting the Houthis since March 15.

Israel’s attacks Tuesday were its second round of airstrikes launched on targets in Yemen in retaliation for a Houthi missile strike Sunday on Israel’s international airport.

The Houthis’ satellite news channel al-Masirah confirmed that the airport in Sanaa was hit on Tuesday. Several power plants also were struck, Israel’s military said. Israeli television aired footage showing black plumes of smoke rising above the Sanaa skyline.

Three people were killed and 38 wounded, according to the Houthi-controlled SABA news agency, which quoted health officials.

The strike against the Sanaa airport came shortly after Israel’s military warned on social media that people should leave the area immediately, saying that “failure to evacuate the area endangers your lives.”

Israel’s defense minister, Israel Katz, said the strike should be seen as a warning to the “head of the Iranian octopus,” which he said bears direct responsibility for attacks by the Houthis against Israel.

The Houthis have targeted Israel throughout the war in Gaza in solidarity with Palestinians there, while also targeting commercial and naval vessels on the Red Sea, raising their profile as the last member of Iran’s self-described “Axis of Resistance” capable of launching regular attacks on Israel.
