Hamas’s political chief Ismail Haniyeh has been assassinated in Iran’s capital, Tehran, according to Iranian state media.

Haniyeh and one of his bodyguards were killed after the building they were staying in was struck, the reports said, quoting a statement from the Islamic Revolutionary Guard Corps (IRGC). The IRGC statement said that Haniyeh was in Tehran to attend the inauguration ceremony of Iran’s President Masoud Pezeshkian, on Tuesday.

Iran’s Revolutionary Guards said Ismail Haniyeh was killed in his Tehran residence along with one of his bodyguards, according to local media reports.

“The residence of Ismail Haniyeh, head of the political office of Hamas Islamic Resistance, was hit in Tehran, and as a result of this incident, him and one of his bodyguards were martyred,” the Islamic Revolutionary Guard Corps’s Sepah news website said.

On May 6, 2017, Hamas, the Palestinian political movement that rules the Gaza Strip, elected Ismail Abdulsalam Ahmed Haniyeh, as the head of its political bureau, replacing Khaled Meshaal.

Earlier this year an Israeli attack killed three of his sons in northern Gaza.
