A senior advisor with Amnesty International Donatella Rovera has said that a lack of resources and continuous airstrikes in Gaza will hinder efforts to investigate human rights abuses.

“The expertise, the skills, the resources — such as the ability to carry out DNA tests — none of that is available [in Gaza], and to make matters worse, there is the constant bombardment,” Rovera told Al Jazeera.

“Where there is evidence of a crime committed yesterday may be destroyed by a bombardment committed today,” she said.

Furthermore, Rovera noted, human rights investigators have not been allowed inside Gaza for years.

“Something can be done immediately that is for the Israeli authority to allow independent investigators immediately, if they have nothing to hide they should have no reason in preventing them in getting into Gaza,” she added.
