Iran says no arrests yet made for Hamas chief's killing

Iran has yet to make any arrests linked to the suspected Israeli killing of Hamas political chief Ismail Haniyeh in Tehran, the Iranian judiciary said Tuesday.

The leader of the Palestinian group was killed last Wednesday during a visit for the swearing-in ceremony of Iranian President Masoud Pezeshkian.

The "necessary investigations" have begun and the results will be announced "as soon as the probe is completed," said judiciary spokesman Asghar Jahangir.

"Until today, no arrests have been made in connection with this case," he said, adding that the investigations involved Iranian military officials.

Iran's Revolutionary Guards said Haniyeh was killed using a "short-range projectile" launched from outside his accommodation in Tehran.

Iran and Hamas have blamed Israel and vowed to retaliate. Israel has declined to comment. 

On Saturday, the New York Times reported that Iran had arrested more than two dozen people, including senior intelligence officers among others, in connection with Haniyeh's killing. 

Jahangir dismissed the claims about any arrests as "rumours" and "false".

"Haniyeh's assassination will definitely be met with a courageous response by the Islamic Republic," he said.
