The Elusive Yahya Sinwar: Hamas Leader Evades Capture Amid Ongoing Conflict

In the nearly five-month-long war between Israel and Hamas, the elusive Yahya Sinwar, the Hamas leader, has continued to evade capture or death, denying Israel a military victory. Sinwar is considered the most important figure in Hamas, and his ability to remain hidden has hindered Israel's efforts to claim a significant military success. The hunt for Sinwar has been a top priority for American and Israeli officials, with both countries pouring vast resources into finding him.

Key Takeaways:

• Sinwar has been living underground in a vast network of tunnels beneath Gaza City, with intelligence agencies able to monitor some of his cellular and satellite phone calls.
• He was initially believed to be living in a tunnel complex in the southern Gaza Strip, but had fled the area before a raid by Israeli commandos in January.
• Sinwar has been using human couriers to stay in touch with Hamas leaders, a playbook used by Hamas leaders in the past and by other terrorist leaders like Osama bin Laden.
• The American and Israeli spy agencies have been working together to intercept Sinwar's communications, with the United States providing ground-penetrating radar to help map the tunnel network.
• Sinwar abandoned electronic communications long ago, making it more difficult for intelligence agencies to track his whereabouts.
• His influence in Hamas grew steadily in the 1980s, and he was named Hamas's leader in Gaza in 2017, with a circle of confidants including Marwan Issa, Rawhi Mushtaha, Izzeldin al-Haddad, Mohammed Sinwar, and Muhammad Deif.
• Mr. Deif was the most senior adviser to Sinwar but was less disciplined and was killed in an airstrike, allowing Western intelligence agencies to pinpoint his whereabouts.
• Sinwar's network of advisers has been steadily shrinking, with some top commanders killed, captured, or unable to return to Gaza.

Statistics:

• At least 1,200 people were killed in the Oct. 7 attacks, including dozens of Israeli civilians and soldiers.
• Sinwar has been living underground in a network of tunnels for over six months, with intelligence agencies able to track some of his movements.
• The tunnel network is vast, with hundreds of miles of tunnels under Gaza, and new imagery combined with Israeli intelligence gathered from captured Hamas fighters and documents to build out a more complete picture of the tunnel network.
• American and Israeli officials have been working together to share information about the location of Sinwar and other top Hamas commanders, including the dozens of hostages still held in Gaza.

Sources:

• "Israeli intelligence and military officials believe that Mr. Sinwar was living in a warren of tunnels beneath Gaza City, the largest city in the strip and one of the first targeted by Israeli military forces."
• "The C.I.A. also set up a task force, and the Pentagon dispatched special operations troops to Israel to advise the Israel Defense Forces on the looming war in Gaza."
• "American officials believe that it would offer Prime Minister Benjamin Netanyahu of Israel a way to claim a significant military victory and potentially make him more willing to end military operations in Gaza."
• "Communicating with Mr. Sinwar has become more difficult, with officials saying that he has not responded to messages within days, and some of his deputies have been his proxies in those discussions."
