''We've been drawing attention to the poor conditions at the Al-Hol camp for some time now, and this is another extremely sad reminder of how bad the conditions are,'' said UN's deputy spokesperson Farhan Haq.
''We continue with our pleas for all parties to do what they can to improve the situation there. And of course, this needs to be thoroughly condemned and thoroughly investigated.''
The bodies of the Egyptian girls were found near the sewage system of the camp, according to the Syrian Observatory for Human Rights.
The monitoring group said the bodies of the two girls, who had gone missing in the past few days, had stab wounds.
The Al-Hol camp is run by the YPG/PKK terror group and houses 55,000 suspected Daesh/ISIS members and their families from Syria, Iraq and 60 other countries with more than half of the residents being children.
The UN has deplored inhumane and degrading conditions at the camp with human rights experts urging nations to repatriate citizens held at the location.
Some countries, including Türkiye, Russia and Kazakhstan have repatriated citizens but Western nations have shown a reluctance to address the situation.
