Battling for their lives. Shes stable, as dad put it. Shes fighting through it. Shes working real hard to get through this. Good day, everyone. Im Andrea Mitchell in washington. Another deadly day. The violence is only escalating in the middle east. Theres been an air strike on a crowded market in gaza. Through reports of at least a dozen or more dead. Earlier this morning a United Nations school was hit killing at least 15 people, mostly women and children. And wounding nearly 100 more sheltering. The u. N. Confirmed the attacks and is placing the blame on israel. Israel has not officially accepted or denied the blame. Joining me for the latest from the ground im joined by Ayman Mohyeldin and martin fletcher. First to you, ayman. Tell us about this deadly day today. Theres been two separate incidents today. Well start with the most recent one that happened within the last 90 minutes. It was at a market thats already been heavily shelled and destroyed over the course of the past week.
