DEIR AL-BALAH, Gaza Strip (AP) — Israel launched another round of heavy airstrikes in Yemen on Wednesday, killing dozens just days after Houthi rebels carried out a drone attack that struck an Israeli airport.

The strikes killed at least 35 people and wounded more than 130 others, the Houthi-run health ministry said. Search crews were continuing to dig through the rubble.

Most of those killed were in Sanaa, the capital, where a military headquarters and a fuel station were among the sites hit, the health ministry said.

European Commission President Ursula von der Leyen, meanwhile, said she would seek sanctions and a partial trade suspension against Israel over the war in the Gaza Strip. The move adds to Israel’s already unprecedented global isolation as it grapples with the fallout from its strike targeting Hamas leaders in U.S.-allied Qatar on Tuesday.

Al-Masirah, a Houthi-controlled satellite news channel, said one of the strikes on Yemen hit a military headquarters building in central Sanaa. Neighboring houses were also damaged, it reported.

Israel has previously launched waves of airstrikes in response to the Houthis’ firing missiles and drones at Israel. The Iran-backed Houthis say they are supporting Hamas and the Palestinians in the Gaza Strip, and on Sunday, sent a drone that breached Israel’s multilayered air defenses and slammed into the country’s southern airport.

Israel reiterated its calls for some 1 million people to evacuate Gaza City, where it has been bombing high-rises and ramping up a new offensive aimed at taking over the largest Palestinian city, already devastated from earlier raids and experiencing famine.

The Israeli military said Wednesday it soon will increase the pace of targeted strikes near Gaza City as it readies for the next phases of its operation in what it calls Hamas’ last remaining stronghold.

Palestinians have been ordered to head south to a designated safe zone where hundreds of thousands already live in squalid tent camps and where Israel regularly strikes what it says are militant targets. Many have refused to leave Gaza City, saying they no longer have the strength or money to relocate.

“There is no safe zone in the Gaza Strip,” Fawzi Muftah said as people walked alongside a line of vehicles loaded with mattresses, carpets and other belongings. “Danger is everywhere.”

Amal Sobh, displaced with 30 relatives — including 13 orphans — said a three-wheel vehicle carrying their belongings broke down and they have no fuel, leaving them stranded Wednesday.

“We don’t have good blankets or good beddings, and winter is coming, what do we do for our children? We don’t even have a proper tent to shelter us,” said Sobh, whose husband was arrested during the war.

The Gaza Health Ministry said the bodies of another 41 people killed by Israeli fire, including 12 who were seeking humanitarian aid, have been brought to hospitals over the past 24 hours. Another 184 people were wounded, it said.

The 27-nation EU is deeply divided in its approach to Israel and the Palestinians, and it’s unclear whether a majority will be found to endorse the sanctions and trade measures called for by von der Leyen.

Israel’s strikes in Yemen followed earlier attacks that killed the Houthi prime minister and other top officials in a major escalation of the nearly 2-year-old conflict between Israel and the Iran-backed militant group.
