Egyptian President Abdel Fattah al-Sisi met Saudi Arabia's de facto ruler on a brief visit late on Sunday, state media said, as the North African country grapples with severe economic difficulties.

Sisi was greeted at Jeddah airport by Crown Prince Mohammed bin Salman and was waved off again several hours later by the 37-year-old, according to the Saudi Press Agency.

Few details were given about the meeting, but import-dependent Egypt's economic fortunes have plunged since Russia's invasion of Ukraine sent wheat prices soaring, fuelling rampant inflation.

Tunisian President Kais Saied appeared in a video posted Monday on his official Facebook page, dismissing "mad" reports over his health following almost two weeks with no public engagements.

The North African country's main opposition coalition had pressed the government earlier to explain Saied's public "absence", saying it had information that he was sick.

"These people deserve nothing but contempt," Saied said in the video, referring to his political rivals.

"The president is absent for two or three days, he gets a cold and that becomes a problem, a power vacuum?"

Russia alleged on Monday the "terrorist attack" that killed a top military blogger the day before was orchestrated by Ukraine with the help of supporters of jailed Kremlin critic Alexei Navalny.

Russian investigators detained 26-year-old Darya Trepova, who was said to have links to Navalny, and posted a video in which she is heard saying she brought to the cafe a statuette rigged with an explosive device.

The trial of a 69-year-old Lebanese-Canadian charged over a fatal 1980 bomb attack outside a Paris synagogue opened on Monday after more than four decades of legal wrangling.

Canada-based Hassan Diab, who denies any involvement in the attack which killed four and wounded dozens, told the court during preliminary hearings that he would not show up for the trial, after accusations against him had been dropped in an earlier investigation.

Israeli forces shot dead two Palestinians Monday in a morning raid in the occupied West Bank, the Palestinian health ministry said, in what the army described as "counterterrorism activity".

"Two martyrs shot by the occupation (Israel) in Nablus," the ministry confirmed in a brief statement, without elaborating on their identities.

The Israeli army said it had carried out the raid to apprehend two individuals linked to a shooting attack in which two Israeli soldiers were injured last month in the West Bank town of Huwara.

A former headmistress was found guilty on Monday of sexually assaulting two sisters at an ultra-orthodox Jewish school in Australia, 15 years after she escaped arrest by fleeing to Israel.

Malka Leifer was guilty on 18 charges, the jury said, including raping a student during a sleep-over and sexually assaulting another teenage pupil during a school camp.

She was cleared of a further nine charges.

Leifer was the principal of the Adass Israel School in Melbourne when she was first accused of sexual assault in 2008.

The family of an Arab Israeli medical student shot dead by police at Jerusalem's Al-Aqsa mosque compound rejected on Sunday claims by the force that he grabbed and fired an officer's gun.

Medical student Mohammed al-Asibi was killed late Friday, hours after worshippers marking the Muslim holy month of Ramadan held prayers at the sacred site.

Israeli police said the 26-year-old "managed to take the gun (from an officer) and fire two bullets" before being shot dead by officers.

Major oil powers led by Saudi Arabia announced a surprise production cut of more than one million barrels per day on Sunday, calling it a "precautionary" move aimed at stabilising the market.

The reductions, on top of a Russian decision to extend a cut of 500,000 barrels per day, and despite US calls to increase production, risk stoking inflation and pressure to raise interest rates.

The United Nations' Yemen envoy warned on Sunday the war-ravaged country faces a "critical time" and urged steps towards lasting peace, exactly a year since a truce has dramatically reduced fighting.

Swedish diplomat Hans Grundberg called the UN-brokered truce that took effect in April 2022 a "moment of hope" and said it was largely holding, despite lapsing in October.

Britain's interior minister Suella Braverman on Sunday said the UK government was "in negotiations" after three British men were detained by the Taliban in Afghanistan.

Media reports have identified the men as charity medic Kevin Cornwell, 53, the unnamed manager of a hotel for aid workers and YouTube star Miles Routledge.

Scott Richards, co-founder of the non-profit group the Presidium Network, told AFP his organisation was representing the families of two of the three detainees.
