Hamas leader Haniyeh

Iran's Supreme Leader Ayatollah Ali Khamenei led a funeral for Hamas leader Ismail Haniyeh in Tehran, weeping over the coffin and vowing revenge against Israel for his assassination. Haniyeh was killed in an Israeli airstrike while attending the inauguration of President Masoud Pezeshkian, sparking outrage in Iran, where Khamenei promised a 'harsh punishment' for Israel. The funeral drew thousands of mourners who chanted anti-American and anti-Israel slogans, underscoring the tensions in the region. Khamenei's call for retaliation comes amid concerns that Haniyeh's death could derail ongoing ceasefire negotiations related to the Gaza conflict. Israeli officials claimed the assassination was a significant blow to Hamas, with Prime Minister Netanyahu warning of a heavy price for any aggression against Israel. The events have heightened fears of escalating violence in an already volatile region.
