Iran holds symbolic funeral for Hamas leader killed in Tehran

Iran has vowed to avenge the death of Hamas leader Ismail Haniyeh, who was killed in an attack on his residence in Tehran.
While Israel has not claimed responsibility, Iranian authorities and Hamas officials have blamed the Jewish state for the attack.
Since at least 2010, Israel has allegedly conducted dozens of attacks inside Iran, including sabotage of sensitive nuclear and military installations, as well as assassinations of experts and individuals deemed a threat.
Haniyeh was killed after attending the inauguration ceremony of Iran's new president and meeting with Iran's Supreme Leader Ali Khamenei.
His assassination has stoked fears of the escalation of tensions into a full-fledged regional war.
