The Sana'a-based National Social Party on Wednesday condemned the brutal massacre committed by the Israeli army in Mawasi Khan Younis, leaving 40 civilians killed and over 60 others injured.This crime, along with all daily carnages and ethnic cleansing committed against the Palestinian people, would not occur or persist without American support, the Party said in a statement seen by Saba.The Zionist lingering crimes are emboldened by the lack of international firm actions, impunity and need to apply the international human law on this criminal entity, the statement read.The Party held the international community, UN and its Security Council, and the U.S. administration full responsible for this slaughter that persisted over 11 months.Source: Yemen News Agency
