Israel struck a declared safe zone in Gaza on Tuesday, in a strike the Hamas-run territory's health ministry said killed at least 19 people and the Israeli military said targeted Palestinian militants.

The strike hit Al-Mawasi in the southern Gaza Strip, which Israel had designated as a "humanitarian zone" early in the war, and prompted condemnations from the region and beyond.

Samar al-Shair, one of tens of thousands of displaced Palestinians who have sought refuge in the coastal area, said the attack came "as we were sleeping in our tents".

Jordanians voted Tuesday in a parliamentary election overshadowed by the Gaza war and concerns over a slump in tourism, a sector vital to the kingdom's economy.

It is the first vote since a 2022 reform increased the number of seats in the house, reserving more for women and lowering the minimum age for candidates.

Despite these efforts to modernise the legislature, voters and candidates said the war in the Gaza Strip dominated the election.

After voting, Prime Minister Bisher Khasawneh said he hoped the turnout would not be affected by "this brutal Israeli aggression".

An abandoned tanker carrying more than one million barrels of crude oil could contaminate vast areas of the Red Sea in a severe, long-term environmental disaster if it breaks up or explodes, experts warn.

The Greek-flagged Sounion, struck on August 21 by Yemen's Huthi rebels, was still on fire as recently as Saturday, maritime monitors said.

Gaza's civil defence agency said Tuesday that an Israeli strike on a humanitarian zone in the south of the Palestinian territory killed 40 people and wounded 60 others, with the Israeli army saying it had targeted a Hamas command centre in the area.

The strike hit Al-Mawasi -- in Gaza's main southern city of Khan Yunis -- which was designated a safe zone by the Israeli military early in the war, with tens of thousands of displaced Palestinians seeking refuge there.

Russian Foreign Minister Sergei Lavrov visited Riyadh on Monday where he met with Saudi Arabia's de facto ruler Crown Prince Mohammed bin Salman and other officials from the six-nation Gulf Cooperation Council.

Gulf monarchies have strived to remain neutral in the ongoing war between Ukraine and Russia.

The talks between the Saudi prince and Russian minister focused on "recent international and regional developments," the official Saudi Press Agency reported.

Near the usually quiet Syrian town of Masyaf smoke was still billowing from trees while burnt-out cars stood nearby, a day after authorities reported deadly Israeli strikes on military sites.

Syrian health minister Hassan al-Ghabash told AFP the overnight "Israeli aggression" killed 18 people and wounded 37 others, during a media tour organised by the authorities.

At the entrance to the mountainous town, about 220 kilometres (135 miles) north of the capital Damascus, a partially burned sign read "Masyaf".

The two unsuccessful candidates in Algeria's presidential election contested on Monday the turnout and percentage of votes they won in the weekend ballot, denouncing a "fraud".

Speaking to reporters in the capital Algiers, Islamist candidate Abdelaali Hassani nonetheless conceded to incumbent President Abdelmadjid Tebboune, who won with a landslide of nearly 95 percent of the vote on Saturday, according to the country's electoral authority, ANIE.

Hassani, who heads the moderate Islamist party the Movement of Society for Peace, said he had "lost the battle but not the war".

Hundreds of mourners gathered Monday in Nablus, in the occupied West Bank, to pay respects to a US-Turkish activist killed while protesting Israeli settlements in a nearby town.

The body of the 26-year-old activist, Aysenur Ezgi Eygi, was wrapped in a Palestinian flag, with her head covered by a keffiyeh, a traditional scarf symbolising the Palestinian struggle against Israel.

Palestinian security forces carried her body through the streets of Nablus, accompanied by the sound of Palestinian bagpipes before a wreath was placed over her remains as a trumpet sounded.

The European Union said Monday its allies had shared "credible" intelligence that Iran had supplied Russia with ballistic missiles, a move Washington warned would be met with "significant consequences".

The claim was rejected by Tehran but not explicitly denied by the Kremlin. EU and US officials said that, if true, it would constitute a major "escalation" of Iran's support for Moscow in its invasion of Ukraine.

US media outlets reported last week that Washington believed Iran had transferred the weapons to Russia for use in Ukraine, citing anonymous sources.

A Lebanese judge Monday issued an arrest warrant for ex-central bank chief Riad Salameh, a judicial official said, after the embattled former governor was questioned in an embezzlement case.

Salameh, 74, who headed the central bank for three decades, faces numerous charges including embezzlement, money laundering and tax evasion in separate probes in crisis-hit Lebanon and abroad.

The most senior Lebanese figure to be arrested in the wake of the country's dramatic economic collapse in 2019, Salameh has repeatedly denied any wrongdoing.
