Israeli airstrikes targeting residential buildings, displaced people and health care workers in Lebanon may violate international law and could amount to war crimes, the U.N. human rights office said Tuesday.

The Israeli military has been ​carrying out ⁠airstrikes in Lebanon since it was dragged into the U.S.-Israel war on Iran by the Tehran-backed Hezbollah.

Israel's strikes have killed at least 886 people in Lebanon and forced more than 1 million from their homes, according to Lebanese authorities.

"Israeli airstrikes have destroyed entire residential buildings in dense urban environments with multiple members of the same family, including women and children, often killed together," U.N. human rights office spokesperson Thameen al-Kheetan told reporters in Geneva.

The Israeli military was not immediately available for comment on his remarks.
