In an ongoing all-out war against Hamas terrorists, Israel killed its Hamas Chief Ismail Haniyeh in Tehran on July 30. Haniyeh, who usually resides in Qatar, was in the Iranian capital for the inauguration of President-elect Pezeshkian. Known for his role in strengthening Hamas and his close ties with Iran, Haniyeh had suffered personal losses earlier this year when an Israeli airstrike killed three of his sons and four grandchildren. Haniyeh also paid tribute to former Iranian President Ebrahim Raisi, who died in a helicopter crash. This latest action marks a significant escalation in the ongoing conflict between Israel and Hamas. Watch video for more.
