In a letter addressed to United Nations Relief and Works Agency for Palestine Refugees (UNRWA) Commissioner-General , Pierre Krahenbuhl , Mustafa said the tragic situation of Palestinian refugees at camps in Syria necessitates exerting all efforts by the UN Secretary-General to force terrorists to fully withdraw from al-Yarmouk camp and other camps for residents to come back in peace and security under the protection of the Syrian government.

Mustafa pointed out that armed terrorist groups have recently carried out a barbaric attack on Danoun Camp and killed and injured scores of Palestinian refugees in an attempt to liquidate the Right to Return which was guaranteed by the UN resolutions, particularly resolution No. 194 for 1948.
