Hamas says its leader killed in Israeli strike

Assassination in Iran prompts outcry and sparks concerns of wider regional conflict

Hamas said on Wednesday its political leader Ismail Haniyeh was killed in an Israeli strike in Teheran and vowed the act "will not go unanswered".

Iran's Islamic Revolutionary Guard Corps confirmed in a statement the death of Haniyeh, hours after he attended a swearing-in ceremony for the country's new President Masoud Pezeshkian.

The statement said Haniyeh's residence in Teheran was hit and he was killed along with a bodyguard, adding the attack is under investigation and details will be released later.
