TODAY SECURITY AT NYU REMAINS TIGHT ON THAT CAMPUS AND APPLY WOULD WALL NOW BLOCKS THE PLAZA. >> NANCY, THANK YOU SO MUCH FOR YOUR REPORTING. >>> NOW TO WHAT THE STUDENTS THERE AT UNIVERSITIES ACROSS THE COUNTRY ARE PROTESTING, OF COURSE, AS WE HAVE BEEN COVERING THE WAY THE WAR HAS UNRAVELED IN GAZA, KILLING MORE THAN 30,000 PEOPLE, MOST OF THEM WOMEN AND CHILDREN. AUTHORITIES NOW CLAIM TO HAVE FOUND A MASSIVE GRAVESITE AT THE MEDICAL FACILITY IN KHAN YOUNIS IN GAZA. >> THE U.N.'S HUMAN RIGHTS CHIEF SAID HE IS HORRIFIED BY THE DISCOVERY. MORE THAN 200 BODIES ARE SAID TO BE FOUND AT THE HOSPITAL FOLLOWING THE CONCLUSION OF THE ISRAELIS MILITARY OPERATIONS IN THE AREA. OUR CORRESPONDENT IS HERE NOW WITH MORE FROM JERUSALEM. WHAT ARE WE LEARNING FROM THESE REPORTS OF THESE MASS GRAVES FOUND THE OTHERS HOSPITAL IN KHAN YOUNIS? >> Reporter: HELLO, BEN IN LILIA. EARLIER IN THE WAR, ISRAELI TROOPS SPENT SEVERAL WEEKS STORMING AND SEEDING THIS HOSPITAL IN KHAN YOUNIS IN SOUTHERN GAZA. THOSE ISRAELI TROOPS ON THE GROUND WITHDREW EARLIER THIS MONTH. THAT ALLOWED LOCAL OFFICIALS IN. THEY SAID THEY FOUND ALMOST 300 BODIES, SOME OF THE BODIES, THEY ALLEGE, SHOW SIGNS OF TORTURE AND HAVE BEEN REBURIED. THE U.N. HUMAN RIGHTS CHIEF SAYS HE IS HORRIFIED BY THESE REPORTS AND THAT THE BODIES MAY HAVE BEEN REBURIED AND HE IS CALLING FOR AN INDEPENDENT INVESTIGATION. ISRAEL HAS COMPLETELY REJECTED THESE ACCUSATIONS, SAYING IT IS BASELESS AND ISRAELI TROOPS, UPON FINDING THE BODIES, CHECK THEM OVER CAREFULLY TO CHECK THEY WEREN'T ACTUALLY DEAD ISRAELI HOSTAGES, ACCORDING TO ISRAEL, THEY WERE THEN RETURNED TO THE PLACE THEY WERE VERY. OF COURSE, ANOTHER SIGN OF FURTHER TENSION BETWEEN ISRAEL AND U.N. OVER THE OPERATIONS IN GAZA. >> ON THAT NOTE, ISRAEL CONTINUES TO CARRY OUT AIRSTRIKES ON RAFAH. WHAT DO WE KNOW ABOUT WHEN THE MILITARY CAN BEGIN THAT MUCH ANTICIPATED GROUND INVASION IN GAZA'S SOUTHERN CITY AND WHERE THE MAJORITY OF PEOPLE ARE ASKED >> Reporter: YES, INDEED. ABOUT 1.5 MILLION INTERNALLY DISPLACED REFUGEES, PALESTINIANS, IN AND AROUND RAFAH. ALLIES HAVE URGED ISRAEL NOT TO UNDERTAKE THIS FULL-SCALE MILITARY OPERATION BECAUSE OF CONCERN, REALLY, BECAUSE OF THE DIRE HUMANITARIAN SITUATION. PRIME MINISTER BENJAMIN NETANYAHU HAS SAID THE MILITARY INCURSION WILL GO AHEAD BECAUSE HE CANNOT SAY THE WAR IS OVER. HE CANNOT SAY HAMAS HAS BEEN DEFEATED UNTIL THAT HAPPENS. ACCORDING TO THE ISRAELI, THE REMNANTS OF THE HAMAS FIGHTERS AND HAMAS LEADERS ARE THERE IN AND AROUND RAFAH IN SOUTHERN GAZA. IT IS AN ISRAELIS HOLIDAY, PASSOVER JUST STARTED TODAY. MANY PEOPLE DON'T EXPECT THE FULL OPERATION TO BEGIN UNTIL THE END OF PASSOVER BUT CBS IS INSISTING IT WILL HAPPEN. >> THE U. S. IS CONSIDERING SANCTIONS OVER AN INDIVIDUAL IDF UNIT OVER HUMAN RIGHTS VIOLATIONS. THAT IS UNUSUAL. WHEN COULD THIS HAPPEN? >> Reporter: YEAH, IT IS UNUSUAL BECAUSE THIS, I THINK, REFERS TO THINGS THAT HAPPENED A FEW YEARS AGO. IT DEMONSTRATES SOME OF THE TENSIONS BETWEEN WASHINGTON AND THE ISRAELI. THIS IS A RELIGIOUS BATTALION AND THEY ARE ALLEGED TO HAVE CARRIED OUT HUMAN RIGHTS ABUSES AGAINST DETAINEES IN THE OCCUPIED PALESTINIAN WEST BANK, INCLUDING AN AMERICAN PALESTINIAN, AN EIGHT-YEAR-OLD WHO DIED TWO YEARS AGO. WE UNDERSTAND FROM THE STATE DEPARTMENT THEY ARE CONSIDERING CERTAIN SANCTIONS AGAINST THIS
