Israeli forces may have committed war crimes during the 11-day war with Hamas, said UN High Commissioner for Human Rights Michelle Bachelet.
She also called on Israel to allow an independent investigation into hostilities in the latest escalation of the conflict, AP reported.
Indiscriminate rocket attacks against Hamas during the conflict are also a clear violation of the rules of war, she said. She detailed to the Human Rights Council about the most significant escalation of hostilities since 2014, which led to the destruction and loss of life in the Gaza Strip prior to the ceasefire last week.
The 11-day war in Gaza killed at least 248 people, including 66 children and 39 women. In Israel, 12 people died, including two children.
Airstrikes in densely populated areas have resulted in high levels of civilian casualties and injuries, as well as widespread destruction of civilian infrastructure, Bachelet said.
Such attacks may constitute war crimes if they are considered indiscriminate and disproportionate in their impact on the civilian population, she added.
She also criticized Hamas' tactics, which included placing military targets in densely populated civilian areas and firing rockets from them.
