Hamas leader Yahya Sinwar, a mastermind of the Oct. 7, 2023 attack on Israel that triggered the war in Gaza, has been killed in a military operation.
His death would be a significant moment in Israel's yearlong offensive against the militant group and could complicate efforts to release dozens of hostages held in Gaza.
Sinwar became the head of Hamas after the killing of the previous leader, Ismail Haniyeh, in an explosion in Iran in July that was widely blamed on Israel.
Some things to know about Sinwar:
From refugee camp to Hamas militant Sinwar was born in 1962 in a refugee camp in the Gaza town of Khan Younis. He was an early member of Hamas, which was formed in 1987. He eventually led the group's security arm, which worked to purge it of informants for Israel.
Israel arrested him in the late 1980s and he admitted to killing 12 suspected collaborators, a role that earned him the nickname “The Butcher of Khan Younis.” He was sentenced to four life terms for offenses that included the killing of two Israeli soldiers, The Associated Press reported.
A prison leader Sinwar organized strikes in prison to improve working conditions. He also studied Hebrew and Israeli society.
He survived brain cancer in 2008 after being treated by Israeli doctors.
Sinwar was among more than 1,000 Palestinian prisoners released in 2011 by Prime Minister Benjamin Netanyahu as part of an exchange for an Israeli soldier captured by Hamas in a cross-border raid.
When Sinwar returned to Gaza, he quickly rose through Hamas' leadership ranks with a reputation for ruthlessness. He is widely believed to be behind the 2016 killing of another top Hamas commander, Mahmoud Ishtewi, in an internal power struggle.
Sinwar became head of Hamas in Gaza, effectively putting him in control of the territory, and worked with Haniyeh to align the group with Iran and its proxies around the region while also building the group's military capabilities.
There is widespread evidence that Sinwar, along with Mohammed Deif, the head of Hamas’ armed wing, engineered the surprise Oct. 7 attack on Israel.
The International Criminal Court’s prosecutor sought arrest warrants in May for Sinwar, Deif and Haniyeh for their alleged roles in the attack.
Israel said it killed Deif in a strike in July, while Hamas says he is still alive.
Where would this leave Hamas? Sinwar has been in hiding since the attack, and cease-fire negotiators have said it can take several days to send and receive messages from him.
Even before becoming Hamas' top leader, Sinwar was believed to have the final word on any deal to release hostages held by the militant group. Some 100 hostages remain in Gaza, around a third of whom are believed to be dead.
It's unclear who would replace Sinwar, and what that might mean for the cease-fire efforts, which sputtered to a halt in August after months of negotiations brokered by the United States, Egypt and Qatar.

Inside Hezbollah’s Kamikaze Drone That Hit Israel's Binyamina

The Israeli security apparatuses are investigating the type of kamikaze drone that Hezbollah used on Sunday evening to hit a Golani Brigade base near Binyamina south of Haifa, killing four soldiers and wounding about 90 others, including 12 soldiers with serious injuries.

Ron Ben-Yishai, a security expert at the Yedioth Ahronoth newspaper, said that from the limited details currently available, the drone was likely a Sayyad 107 model, a UAV manufactured in Iran and widely used by Hezbollah, which also produces it in large quantities in Lebanon.

“The model’s flight path can be programmed to frequently change altitude and direction, making it difficult to detect and track,” Ben-Yishai said.

“It has a range of up to 100 kilometers (62 miles) and is small, with a very low radar signature compared to larger, metal-made UAVs. Its detection relies on the heat emitted by the engine, which is also challenging to identify via optical means,” he added.

According to the security expert, the military is examining all possibilities, but it's almost certain that the UAV, which hit a critical target and caused many casualties, wasn't only a specialized model but also Hezbollah managed to overwhelm or disrupt the Israeli army’s detection systems by launching a mixed salvo of rockets and two other drones aimed at the Western Galilee.

Ben-Yishai noted that the UAVs continued toward the sea off the northern coast and the Iron Dome system intercepted one.

The Israeli army dispatched fighter jets and combat helicopters to track the remaining UAV, but contact with it was lost, he said.

The expert said it is possible that the UAV was pre-programmed to sharply descend toward the ground or the sea and continue flying at low altitude, exploiting the coastal terrain and then the hills of the coastal plain to evade interceptors.

“Hezbollah has gained considerable experience in operating UAVs over the past year, successfully causing numerous casualties among civilians and primarily IDF soldiers at remote bases,” Ben-Yishai wrote, adding that over half of the drones launched by Hezbollah are intercepted, either by the Israeli army fighter jets sent to engage them or by the Iron Dome and David's Sling systems.

However, he noted, due to the UAV's small size and very weak radar signature, the Iron Dome's fire control radars and the optical sensors on fighter jets and helicopters often lose track of them, especially in hilly areas where radar echoes from the terrain are dominant and misleading.

Ben-Yishai revealed that the Israeli army and defense industries have been trying to find a solution to this issue at least since the current war began, but there is still no effective detection and interception solution.

He said the sophisticated UAVs manufactured by Iran are equipped with inertial navigation systems in addition to satellite navigation, enabling them to stay on course and strike their targets even when faced with GPS jamming.

“This is intended to mislead them, but Iran and Hezbollah sometimes bypass the American GPS jamming by using unique satellite navigation systems developed by Russia or China,” Ben-Yishai said.
