The United Nations said it held talks Monday with rival powers in Libya over the country's central bank crisis which has threatened vital oil income.

The UN Support Mission in Libya hosted the two administrations separately for discussions "marked by open and candid dialogue", it said in a statement.

The "efforts to resolve the crisis" follow a series of events which the eastern administration said were attempts by the Tripoli-based, UN-backed government to seize control of the central bank.

A rescue mission was underway Monday for an oil tanker still ablaze after being attacked by Houthi rebels off the coast of Yemen last month, according to US Central Command.

The Greek-flagged oil tanker Sounion was hit by the Huthis off the coast of Hodeida on August 21 while carrying 150,000 metric tons of crude oil.

In a post on X, CENTCOM said "salvage efforts are underway" in the southern Red Sea for the disabled vessel, "which is still on fire and threatens the possibility of a major environmental disaster."

Tunisia's electoral board said Monday it approved three candidates for an October 6 presidential election, ignoring court rulings that had granted appeals by three other hopefuls who had been rejected.

The three dismissed candidates were among 14 potential contenders to be turned down by the electoral board, ISIE, last month for not obtaining enough endorsements to challenge President Kais Saied.

Last week, the three hopefuls unexpectedly won appeals at the administrative court against ISIE's decision, in a verdict the court called "definitive".

An Israeli strike on a vehicle in south Lebanon killed two people Monday, the health ministry said, nearly 11 months after increased violence between the Iran-backed Hezbollah movement and Israel.

The United Nations Force in Lebanon said one of those killed worked for a cleaning company contracted by UNIFIL.

Hamas ally Hezbollah has exchanged near daily cross-border fire with Israeli forces since the Palestinian group attacked Israel on October 7, triggering the war in Gaza.

"The Israeli enemy's strike targeting a car in Naqura left two dead," the health ministry said.

A strike on Monday called by Israel's largest labour union shuttered parts of the country to pressure the government into reaching a Gaza deal to free hostages, though several sectors were unaffected.

The Histadrut trade union called a nationwide strike beginning at 6:00 am (0300 GMT), a day after mass demonstrations following the army's announcement that troops had recovered the bodies of six hostages "murdered" in a Gaza tunnel.

US President Joe Biden on Monday said Israeli Prime Minister Benjamin Netanyahu was not doing enough to secure a deal for the release of hostages taken by Palestinian armed group Hamas.

Asked by reporters at the White House -- where Biden was arriving for a meeting with US negotiators -- if he thought the Israeli leader was doing enough on the issue, the president responded: "No."

Biden's meeting with the negotiators on the hostage-release deal comes after the deaths on Saturday of six captives in Gaza, including an American citizen.

Israeli Prime Minister Benjamin Netanyahu faces mounting international and domestic pressure after the killing in Gaza of six captives, with US President Joe Biden saying he is not doing enough to secure the release of hostages.

Britain said Monday it would suspend some arms exports to Israel, citing a "clear risk" they could be used in a serious breach of international humanitarian law.

Israeli Defence Minister Yoav Gallant said he was "deeply disheartened" by London's decision, while the premier said he sought forgiveness for failing to save the latest hostages killed.

The families of Israeli hostages whose bodies were recovered from Gaza sobbed as they laid their relatives to rest on Sunday at funerals that featured heartfelt eulogies alongside expressions of frustration with the government.

"Almog, my dear son, how much hope we had, how much we prayed that we would get the chance to see you again, to hug you, to enjoy your smile," Almog Sarusi's mother Nira said at the lectern during her son's funeral in the city of Raanana in central Israel.

The head of Israel's powerful Histadrut trade union ordered a "complete strike" in support of Gaza hostages on Monday and urged a deal to secure their release after six more were announced dead.

"We must stop the abandonment of the hostages... I have come to the conclusion that only our intervention can shake those who need to be shaken," Histadrut chairman Arnon Bar-David said in a statement on Sunday.

"Starting tomorrow at six in the morning, the entire Israeli economy will go on complete strike."

Ghadir Hajji rushed to a clinic on Sunday in hopes her five children would be among the first to get vaccinated against polio, which has re-emerged in war-ravaged Gaza.

"They absolutely have to be vaccinated," she told AFP as the family waited in line for a vaccine drive announced after health officials reported last month the first case of polio in the besieged territory in a quarter of a century.

"We received text messages from the ministry of health and we showed up right away."
