GAZA STRIP OVER THE WEEKEND, KILLING DOZENS OF PALESTINIANS, INCLUDING YOUNG CHILDREN. AND THE U.N. SAYS 300,000 PEOPLE HAVE NOW EVACUATED RAFAH AHEAD OF A PROMISED ISRAELI INVASION. ON NBC'S "MEET THE PRESS," SECRETARY OF STATE ANTONY BLINKEN TOLD KRISTEN WELKE THEY'RE CIVILIANS ARE STILL AT RISK. >> THERE HAS TO BE A CREDIBLE PLAN FOR THE CIVILIAN. >> HAVE YOU SEEN A CREDIBLE PLAN? >> WE HAVE NOT. >> FOR THE LATEST, LETTERS GET TO CLAUDIO LAVANGA. BUT FIRST, WE SHOULD WARN YOU, THE IMAGES COMING OUT OF GAZA ARE DISTURBING. CLAUDIO, GOOD MORNING. >> GOOD MORNING, FRANCES. WELL, ACCORDING TO THE PALESTINIANS ON SUNDAY, THERE HAS BEEN HEAVY ISRAELI BOMBARDMENT AND FIGHTING IN THE NORTH OF GAZA AND THE IDF HAS SAID IT KILLED SEVERAL HAMAS MILITANTS THERE, WHICH IS YET ANOTHER PROOF THAT HAMAS HAS MANAGED TO RETURN AND REGROUP INTO AREAS OF GAZA THAT HAVE PREVIOUSLY BEEN DECLARED CLEARED BY ISRAEL SINCE THE START OF THE WAR. MANY OF THE PALESTINIANS ARE STILL FINDING SHELTER, MANY HAD TO BE MOVED FROM OTHER PLACES THEY WERE DISPLACED FROM THE ENCLAVE. WELL, THEY ARE PANICKING IN ANTICIPATION OF THAT IMMINENT ISRAELI INVASION, DESPITE THE CALLS BY MANY ALLIES, INCLUDING THE UNITED STATES TO HOLD FIRE. NOW ANOTHER PERSON NOW IS CALLING FOR A CEASEFIRE IS EHUD OLMERT, WHO IS A FORMER ISRAELI PRIME MINISTER, A FORMER MEMBER OF THE NETANYAHU'S PARTY. HE WROTE AN OPEN OPINION PIECE IN THE NEWSPAPER HAARETZ. LET ME QUOTE YOU A PART OF IT. "ANYONE WHO THINKS IT'S POSSIBLE TO RETURN THE HOSTAGES WITHOUT A CLEAR AND TOTAL CESSATION OF THE WAR IS DELUDING HIMSELF AND THE ISRAELI PUBLIC. PRIME MINISTER BENJAMIN NETANYAHU IS DELIBERATELY AND KNOWINGLY FOILING ANY CHANCE OF REACHING SUCH A DEAL." IM
