British government lawyers do not believe Israel has breached international law in its military response to Hamas's deadly October 7 attack, Foreign Secretary David Cameron said on Tuesday.

But the former prime minister told parliament's Foreign Affairs Committee that some of the things he had seen during the war in the besieged Palestinian territory were "deeply concerning".

"Am I worried that Israel has taken action that might be in breach of international law, because this particular premises has been bombed or whatever?" he said.

US Secretary of State Antony Blinken, Israeli President Isaac Herzog and Middle East leaders will attend a World Economic Forum in Davos next week dominated by the war in Gaza, the WEF said Tuesday.

Argentina's libertarian new president, Javier Milei, French President Emmanuel Macron and Chinese Premier Li Qiang will also be among the headliners at the January 15-19 meeting of the world's political and business elites in the Swiss Alps.

The conflict in the Middle East is set to loom over the annual forum, held this year under the theme "Rebuilding Trust".

French driver Sebastien Loeb bounced back the day after a series of punctures to grab his first win of this year's Dakar Rally, edging Saudi race leader Yazeed Al-Rajhi in Tuesday's fourth stage.

The Prodrive competitor -- a former nine-time world rally champion -- finished 1min 08sec ahead of Toyota's Al-Rajhi after 631km of rolling terrain without major difficulty including a 299km special between Al-Salamiya and Al-Hofuf in Saudi Arabia.

Marie-Pascale Radoux has been waiting for three months for news of her son, Orion, still believed held hostage by Hamas in the Gaza Strip after their October 7 attack in Israel.

A painter living near Toulouse in southwest France, Radoux urged Israel and Palestinian militant group Hamas to reach "a ceasefire, or at least a truce, to allow hostages to be freed".

"There has to be a ceasefire, for the hostages, the civilians, the children, the families, all the hundreds and hundreds of innocent people," the 62-year-old added in an interview with AFP.

Top US diplomat Antony Blinken told Israel Tuesday the toll on Gazan civilians caused by its war against Hamas was "far too high", urging his ally to alleviate their suffering.

More than three months into the deadliest ever Gaza war, Blinken met Israeli Prime Minister Benjamin Netanyahu in Tel Aviv on his fourth round of Middle East crisis diplomacy since the conflict broke out.

Blinken reaffirmed US "support for Israel's right to prevent" a repetition of the unprecedented Hamas attacks of October 7 that sparked the war, State Department spokesman Matthew Miller said.

Lebanon's Iran-backed militant group Hezbollah said it targeted a command base in northern Israel on Tuesday in retaliation for the killings of one of its commanders and a Hamas leader.

Hezbollah said the attack was part of its response to the killings of top field commander Wissam Tawil on Monday and Hamas deputy leader Saleh al-Aruri on January 2.

The Shiite Muslim movement, a Hamas ally, said in a statement that it had targeted the "enemy's northern command centre" in the Israeli city of Safed with "several suicide drones".

Top US diplomat Antony Blinken was set to meet Israeli leaders Tuesday as part of efforts to contain the war in Gaza, a day after strikes in Syria and Lebanon killed high-profile members of Hamas and its ally Hezbollah.

The visit comes as the Israeli military said its campaign against Hamas in the Gaza Strip was shifting into a new phase involving more targeted operations in the territory's centre and south.

Qatar go into the Asian Cup starting on Friday as hosts and holders but the shock axing of Carlos Queiroz as coach last month has thrown their title defence into serious question.

Prior to that, the talk was about how Qatar would right the wrongs of a disappointing early exit from their home World Cup just over a year ago.

Qatar's three straight defeats was the worst performance of any World Cup host in history.

Dabbing away tears, Ghadeer al-Atrash stood before her bulldozed home in a Palestinian village abutting Israeli settlements, a fate feared by hundreds of villagers as Israel ramps up demolitions during wartime.

Destruction of homes built without Israeli-issued permits, which campaigners say are nearly impossible for Palestinians to obtain due to Israel's restrictive planning policy, have roiled occupied territories for years.

US top diplomat Antony Blinken said there was "clear interest" in pursuing relations with Israel after talks in Saudi Arabia on Monday, the latest stop in a tour to calm a region inflamed by the Israel-Hamas war.

Blinken also said all the leaders on his tour, which took him to six countries before heading to Israel, had agreed to work with the US to help Gaza's recovery and long-term stability.

He was speaking after meeting Crown Prince Mohammed bin Salman, the de facto Saudi ruler, in a lavish tent outside Al Ula, a historic oasis town.
