Hamas leader Ismail Haniyeh killed in Tehran in alleged Israeli strike

The articles report that Ismail Haniyeh, the political chief of Hamas, was killed in an Israeli strike in Tehran, Iran. Hamas has blamed Israel for the assassination, which they described as a "severe escalation" that would not achieve its goals. Israel has vowed to kill all leaders of Hamas in response to the group's attack on southern Israel on October 7, which killed 1,200 Israelis. The killing of Haniyeh has raised fears that the war in Gaza could spiral into a broader regional conflict.
