Yemen's Houthi rebels have promised a "huge" retaliation against Israel for a deadly strike on the port of Hodeida, as regional fallout widens from months of war in Gaza.

The Israeli strike, the first claimed by Israel in Yemen, set oil tanks ablaze at the vital port and came a day after the first fatal attack by the Houthis in Israel.

Hezbollah said Saturday's strikes by Israel on its Yemeni allies, the Houthi rebels, marked a dangerous turn nine months into the Gaza war.

"The foolish step taken by the Zionist enemy heralds a new, dangerous phase of a very important confrontation across the entire region," the Iran-backed group said in a statement.

Russia said Sunday that it scrambled fighter jets to prevent two U.S. strategic bomber planes from crossing its border over the Barents Sea in the Arctic.

Israeli Prime Minister Benjamin Netanyahu is to deliver a landmark speech to the U.S. Congress this week as he fights off intense pressure to cut a Gaza war ceasefire deal with Hamas.

Israel's longest-serving premier will on Wednesday become the first foreign leader to address a joint meeting of the two chambers four times -- pulling ahead of Britain's Winston Churchill on three.

Firefighting teams on Sunday were still battling a blaze at the Houthi-run port in Yemen's Hodeida, hours after an Israeli strike on the harbor triggered a massive fire and killed three people, according to the rebels.

U.S. Secretary of State Antony Blinken said Friday that a deal for a ceasefire in Gaza and release of remaining hostages by Hamas is near the "goal line."

"I believe we're inside the 10 yard line and driving toward the goal line" on an "agreement that would produce a ceasefire, get the hostages home, and put us on a better track to trying to build lasting peace and stability," Blinken said at a forum in Colorado.

Israel threatened reprisals after a drone claimed by Yemen's Houthi rebels penetrated its vaunted air defenses and killed a civilian in a Tel Aviv apartment building near a U.S. embassy annex.

The attack drew condemnation from U.N. chief Antonio Guterres and an appeal for "maximum restraint" to avoid "further escalation in the region."

The bodies of four Pakistanis killed in an attack on a Shiite mosque in Oman this week have been repatriated and handed to their families, officials said Friday.

Relatives of the victims were present when the Pakistan International Airlines flights landed at the Islamabad and Lahore airports. Airline spokesperson Abdullah Hafeez said the bodies were repatriated at orders from the government and handed to the victims' relatives for burial.

First came the Israeli military bulldozers, which tore down a quarter of the homes in the West Bank Bedouin village of Umm al-Khair. Then came the settler attacks.

In the aftermath, dozens of people were left homeless and without consistent access to water and electricity. Several were injured from pepper spray and sticks, and the village's water pipe was cut — all, they said, as Israeli soldiers looked on.

The top United Nations court is delivering a nonbinding advisory opinion Friday on the legality of Israel's 57-year occupation of lands sought for a Palestinian state, a ruling that could have more effect on international opinion than it will on Israeli policies.

Friday's hearing comes against the backdrop of Israel's devastating 10-month military assault on Gaza, which was triggered by the Hamas-led attacks in southern Israel. In a separate case, the International Court of Justice is considering a South African claim that Israel's campaign in Gaza amounts to genocide, a claim that Israel vehemently denies.
