An Egyptian appeals court on Monday upheld a one-year jail sentence for opposition politician Ahmad al-Tantawi, who was then arrested "inside the courthouse", lawyer Nabeh Elganadi told AFP.

Tantawi, who had hoped to run against President Abdel Fattah al-Sisi in elections last year, was found guilty of election campaign irregularities in February.

"The sentence at the time was suspended on bail until the appeal today," Elganadi said, adding that Tantawi was arrested as soon as the decision was declared.

Israel faced a wave of international condemnation Monday over a strike that Gaza officials said killed 45 people when it set off a fire that ripped through a tent city for displaced Palestinians.

Israel said it was looking into the "tragic accident" and its impact on civilians after the latest mass casualty event in the Gaza war, which has raged since October 7.

Media watchdog Reporters Without Borders (RSF) said on Monday it had filed a complaint with the International Criminal Court over Palestinian journalists killed or injured in Gaza.

RSF said it was asking the ICC's prosecutor to investigate alleged war crimes committed by the Israeli army against at least nine Palestinian reporters since December 15.

The ICC said in January it was probing potential crimes against journalists since the outbreak of war between Israel and Hamas militants in Gaza, which has cost the lives of more than 100 reporters.

The sister of an Israeli hostage whose body was recovered from Gaza last week struck a solemn tone Sunday as she laid him to rest after thousands attended his funeral.

"I feared this ending but I wanted so much for it to end differently," Avivit Yablonka told AFP at the funeral of her brother Chanan.

Chanan, 42, was murdered on October 7 in Hamas's unprecedented attack, while trying to escape from the Nova music festival where at least 364 people were killed.

EU foreign policy chief Josep Borrell on Sunday hosted Palestinian prime minister Mohammed Mustafa for international talks on building up the Palestinian Authority to eventually take over Gaza rule from Hamas.

A "strong" Palestinian Authority is needed to bring peace in the Middle East, Borrell said just before going into the meeting with Mustafa.

The talks were being held as efforts were narrowing to try to find a Gaza truce and a hostage-release deal.

Recognising the State of Palestine "is justice for the Palestinian people (and) the best guarantee of security for Israel," Spain's foreign minister Jose Manuel Albares said Sunday alongside Palestinian prime minister Mohammed Mustafa.

Welcoming Spain's move, with Norway and Ireland, to recognise the Palestinian state on Tuesday, Mustafa said, "We want to have every country in Europe to do the same."

Hamas and the Palestinian Authority said Israeli strikes on a centre for displaced people killed dozens near the southern city of Rafah on Sunday, while the Israeli army said it had targeted Hamas militants.

The health ministry in the Hamas-run territory said in a statement that the strikes "claimed the lives of 35 martyrs and left dozens injured, most of them children and women".

The Hamas-run government media office in Gaza earlier said the attack hit a centre run by the UN agency for Palestinian refugees near Rafah, branding it a "horrific massacre".

In a Beirut car park, migrant workers cheer as their teams face off in a cricket tournament, a moment of respite in crisis-hit Lebanon, where working conditions are often tough.

"Sunday we are so happy... We eat together, we laugh together," said cricketer Pradeepa Silva, a 42-year-old Sri Lankan, as she and her teammates prepared coconut rice and other traditional food nearby to share.

"Work is very tiring" and workers are stressed and worried, said Silva, who is employed as a housemaid six days a week and pays for her daughter's university studies back home.

Thousands of Israelis rallied in Tel Aviv on Saturday to demand urgent government action to bring home hostages held in Gaza, after the bodies of several were retrieved.

Protesters observed a minute's silence in Tel Aviv's Hostages Square in honour of the captives whose bodies were recovered by Israeli troops this month, an AFP correspondent reported.

The army said on Friday that troops had retrieved the bodies of three hostages in an overnight operation in Jabalia in the northern Gaza Strip.

Hernan Crespo's Al Ain steamrollered 10-man Yokohama F-Marinos 5-1 in the Asian Champions League final return leg to lift the trophy for the second time in their history on Saturday.

The hosts trailed 2-1 from the away fixture but two goals from Soufiane Rahimi, a Kaku penalty and Kodjo Laba's late double ensured a 6-3 aggregate victory after Yokohama goalkeeper William Popp saw red just before half-time.

Al Ain, the oil-rich United Arab Emirates' most successful club, won the inaugural Champions League final in 2003 and were runners-up in 2005 and 2016.
