The body of Ismail Haniyeh, the political bureau chief and leader of Hamas, will be interred in Qatar following a funeral in Tehran, Iranian media reported. The ceremony is expected to take place tomorrow.

Haniyeh was assassinated early Wednesday morning at his residence in Tehran, according to an official statement from Hamas confirming his death.

Reports from Iranian media indicate that the deputy secretary-general of the Palestinian Islamic Jihad movement has described Haniyeh’s assassination as a “great loss.”

Iranian authorities have yet to provide details about Haniyeh’s residence, the nature of the attack, or the manner in which it was carried out.
