An Israeli air strike killed a journalist working with Al Jazeera on Monday and the military issued fresh calls to evacuate parts of Gaza's north, as Israel pressed its renewed bombardment and ground operations in the Palestinian territory.

Israel resumed intense air strikes across Gaza last Tuesday, followed by ground operations, after talks on extending a ceasefire with the Palestinian militant group Hamas reached an impasse.

On Monday evening, Israeli military spokesman Avichay Adraee issued "an early warning before a strike" in the northern area of Jabalia.

Sudan's army has recaptured the presidential palace from rival paramilitaries and is pushing ahead to wrest full control of the capital, but analysts warn that the brutal two-year war is far from over.

In the early days of the fighting, the army-aligned government was forced to flee Khartoum, which army forces are now a breath away from regaining -- the result of a counteroffensive launched late last year after a succession of humiliating defeats.

Al Jazeera said on Monday that a journalist working with one of its channels was killed in an Israeli strike on his vehicle in northern Gaza.

"Hussam Shabat, a journalist collaborating with Al Jazeera Mubasher, was martyred in an Israeli strike targeting his car in the northern Gaza Strip," an Al Jazeera alert said, referring to the network's live Arabic channel.

The territory's civil defence agency confirmed his death, as well as that of Muhammad Mansour, an employee of the Islamic Jihad-affiliated Palestine Today TV.

Israel's prime minister, pushing to dismiss internal security chief Ronen Bar, alleged on Monday there had been an attempt to bring down his government after Israeli media reported Bar's agency spent months probing far-right infiltration of the police.

The police are under the supervision of far-right National Security Minister Itamar Ben Gvir. The minister opposed a ceasefire in Gaza but rejoined the government last week when Israel resumed intensive bombing of the Palestinian territory in its war against Hamas.

Vast crowds of students surged onto Istanbul's streets Monday in the latest protest over the arrest and jailing of Istanbul's opposition mayor that has sparked Turkey's worst unrest in years.

The demonstrations began after Ekrem Imamoglu's March 19 arrest and have since spread to at least 55 of Turkey's 81 provinces, sparking clashes with riot police and drawing international condemnation.

Police have arrested more than 1,130 people over the past six days, including 43 on Monday night, the interior minister said. Among them are journalists, including an AFP photographer.

Doctors Without Borders (MSF) denounced on Monday the "extremely precarious" situation of Palestinians displaced by the ongoing Israeli military operation in the occupied West Bank.

According to the United Nations, some 40,000 residents have been displaced since January 21, when the Israeli army launched an operation targeting Palestinian armed groups in the north of the territory.

The West Bank, occupied by Israel since 1967, is home to about three million Palestinians as well as nearly 500,000 Israelis living in settlements that are illegal under international law.

A meeting between Russian and US officials on a partial ceasefire in Ukraine ended after 12 hours of negotiations in Saudi Arabia, Russian state media said, as both sides in the conflict reported a wave of fresh attacks.

While the talks took place at a luxury hotel in Riyadh, nearly 90 people including 17 children were wounded in a missile attack Monday on Sumy in northeastern Ukraine, President Volodymyr Zelensky said.

The leaders of 22 Indigenous peoples from five continents held prayers for nature in Chile on Sunday at the end of a 46-day pilgrimage around the world.

The "Indigenous sages" carried out an ancestral ceremony of the Anasazi people, who lived in the Chaco Canyon before European settlement in what was to become the US state of New Mexico.

It was a ritual that, for the first time, brought together peoples from all over the planet -- travelling together on a journey that began in Italy and passed through India, Australia, and Zimbabwe before concluding in Chile.

An Israeli air strike on Sunday killed a member of Hamas's political bureau as he underwent treatment in hospital, a source in the Islamist movement said, after Israel confirmed it targeted "a key terrorist".

"The Israeli army assassinated Hamas political bureau member Ismail Barhoum," the Hamas source said, requesting anonymity to speak more freely.

"Warplanes bombed the operating room at Nasser Hospital in Khan Yunis, where Barhoum was receiving treatment after sustaining critical injuries in an air strike targeting his home in Khan Yunis at dawn last Tuesday."

Israel's cabinet passed a vote of no confidence on Sunday in the attorney general, the justice minister said, moving against a vocal critic of Prime Minister Benjamin Netanyahu and deepening a political rift in the country.

The vote against Attorney General Gali Baharav-Miara is the first step in a process to dismiss her, and came two days after the government fired the head of the country's internal security agency.
