The killing of Hamas deputy leader Saleh al-Arouri by an Israeli drone strike in Lebanon's capital Beirut has raised the potential risk of the war in Gaza spreading well beyond the Palestinian enclave.
Arouri, 57, was the first senior Hamas political leader to be assassinated since Israel launched a shattering air and ground offensive against the group almost three months ago after its shock assault and rampage into Israeli towns.
Israel has long accused Arouri of lethal attacks on its citizens, but a Hamas official said he was also "at the heart of negotiations" conducted by Qatar and Egypt over the outcome of the Gaza war and the release of Hamas-held Israeli hostages.
Israel neither confirmed nor denied carrying out the killing, but its military spokesperson Rear Admiral Daniel Hagari said Israeli forces were in a high state of readiness and prepared for any scenario.
Since the war broke out on October 7, that killed 1,200 people, more than 22,000 Palestinians have died in Gaza.
Israel has vowed to keep fighting until it has wiped out Hamas and secures the release of its hostages.
Iran could be producing enriched uranium in a few months, the head of the UN nuclear watchdog Rafael Grossi was quoted as saying on Sunday, raising doubts about how effective US strikes to destroy Tehran's nuclear programme have been.
The Jerusalem District Court has cancelled this week's hearings in Prime Minister Benjamin Netanyahu's long-running corruption trial, accepting a request the Israeli leader made citing classified diplomatic and security grounds.
The Israeli military ordered Palestinians to evacuate areas in northern Gaza on Sunday before intensified fighting against Hamas, as US President Donald Trump called for an end to the war amid renewed efforts to broker a ceasefire.
Russia used hundreds of drones, cruise and ballistic missiles to attack western, southern and central Ukraine overnight, damaging homes and infrastructure and injuring at least six people, local authorities said on Sunday.
