A declaration adopted by consensus among 126 of the 196 parties to the Fourth Geneva Convention insists that international humanitarian law must be followed in areas affected by the conflict between Israel and the Palestinians.
The Geneva Conventions govern the rules of war and military occupation. Nations that took part in a one-day conference in Geneva "emphasize that all serious violations of international humanitarian law must be investigated and that all those responsible should be brought to justice," according to the 10-point declaration.
"This is a signal and we can hope that words count," Fivat said. The declaration emphasizes one aspect of the Geneva Conventions: a prohibition on colonizing occupied land.
Israel contends the prohibition shouldn't apply to the West Bank and Gaza because their sovereignty is in limbo, with Jordan and Egypt no longer claiming them and the Palestinians never having their own state.
Another concern raised in the declaration is that Israel should "fully and effectively" respect the Fourth Geneva Convention, meant to protect civilians during times of war including in East Jerusalem and other occupied territories.
Israel opposed the move, arguing there is no universally recognized Palestinian state and it would complicate peace talks.
The UN General Assembly upgraded Palestine to a "non-member observer state" of the world body in 2012.
