According to Iran International Television, on July 31, local time, the Public Relations Department of the Islamic Revolutionary Guard Corps of Iran stated that the leader of the Hamas Political Bureau, Ismail Haniyeh, and a bodyguard were assassinated in Tehran, the capital of Iran. Both were killed in an attack at their residence in the early morning of the 31st.
According to Xinhua News Agency, Hamas issued a statement on the 31st saying that Hamas leader Ismail Haniyeh was killed in an Israeli airstrike at his residence in Tehran, the capital of Iran.

It is inferred that the airstrike should have been launched by a drone, and it happened in the early morning. For drones that strike accurately at night, it is necessary to equip them with thermal imaging Gimbal. This also confirms that in modern warfare, the effect of drones in precision strikes is very prominent.
