The assassination of Hamas leader Ismail Haniyeh in Tehran has escalated tensions in the Middle East, with Iran vowing severe retaliation against Israel. Iranian Supreme Leader Ayatollah Ali Khamenei has ordered a direct strike on Israel, considering various military options, including coordinated attacks with regional allies. The US, despite distancing itself from the assassination, continues to advocate for a ceasefire and regional de-escalation, though its goals seem increasingly unattainable. Russia has condemned the killing, warning that it risks triggering a global conflict. The situation in the region remains highly volatile, with potential for broader military engagements involving multiple nations and non-state actors.
