MEMO is still calling for a prisoner exchange, but the reality is that they are Israeli hostages of all ages, taken as a deliberate violation of the UN Rules of War and Geneva Conventions, after massacring 1200 Israeli men, women, and children, which is the equivalence of an open invitation for Israel to do something about it.
A swap goes against the International Court of Justice who demanded 8 months ago that Hamas release all the hostages “immediately and unconditionally”. Source: International Court of Justice Website.
