Sudanese refugees in Israel

these Sudanese women live in Israel. There are 500 here as legal Immigrants. However an estimated 1160 and another 1,500 Egyptians have arrived here over the desert boarder with Egypt.....a large are without boarder fences. It appears that Israel intends to send the Illegal immigrants back to Egypt. I am sad for them.I understand that they want to live here rather than Egypt but i think Israel has little choice
